+PDF optimization
+----------------
+
+By default OCRmyPDF will attempt to perform lossless optimizations on the images inside PDFs after OCR is complete. Optimization is performed even if no OCR text is found.
+
+The ``--optimize N`` (short form ``-O``) argument controls optimization, where ``N`` ranges from 0 to 3. ``--optimize 0`` disables optimizations. ``1`` enables lossless optimizations that can be performed safely with no quality loss. ``2`` enables lossy optimizations such as image color quantizations. ``3`` enables more aggressive optimizations and targets a lower JPEG quality.
+
+Optimization is improved when a JBIG2 encoder is available and when ``pngquant`` is installed. If either of these components are missing, then some types of images will not be optimized.
+
+Currently optimization attempts to find more efficient encodings for images. The types of optimization available may expand over time. By default, OCRmyPDF compresses data streams inside PDFs, and will change inefficient encodings to more modern versions. A program like ``qpdf`` can be used to change encodings, e.g. to inspect the internals fo a PDF.

+
+.. note::
+
+    OCRmyPDF for Debian and Ubuntu currently omit the JBIG2 encoder. OCRmyPDF works fine without it but will produce larger output files. If you build jbig2enc from source, ocrmypdf 7.0.0 and later will automatically detect it (specifically the ``jbig2`` binary) on the ``PATH``. To add JBIG2 encoding, see `Installing the JBIG2 encoder`_.
+
+Installing the latest version on Ubuntu 18.04 LTS
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Ubuntu 18.04 includes ocrmypdf 6.1.2. To install a more recent version, first
+install the system version to get most of the dependencies:
+
+.. code-block:: bash
+
+    sudo apt-get update
+    sudo apt-get install \
+        ocrmypdf \
+        python3-pip
+
+There are a few dependency changes between ocrmypdf 6.1.2 and 7.x. Let's get
+these, too.
+
+.. code-block:: bash
+
+    sudo apt-get install \
+        libexempi3 \
+        pngquant
+
+Then install the most recent ocrmypdf for the local user and set the user's ``PATH`` to check for the user's Python packages.
+
+.. code-block:: bash
+
+    export PATH=$HOME/.local/bin:$PATH
+    pip3 install --user ocrmypdf
+
+To add JBIG2 encoding, see `Installing the JBIG2 encoder`_.
+
+Ubuntu 16.04 LTS
+^^^^^^^^^^^^^^^^
+
+No package is currently available for Ubuntu 16.04, but you can install the dependencies manually:
+
+.. code-block:: bash
+
+    sudo apt-get update
+    sudo apt-get install \
+        ghostscript \
+        libexempi3 \
+        pngquant \
+        python3-cffi \
+        python3-pip \
+        qpdf \
+        tesseract-ocr \
+        unpaper
+
+If you wish install OCRmyPDF for the current user, and ensure that the ``PATH``
+environment variable contains ``$HOME/.local/bin``.
+
+.. code-block:: bash
+
+    export PATH=$HOME/.local/bin:$PATH
+    pip3 install --user ocrmypdf
+
+Alternately, you can install ocrmypdf system-wide. (Not recommended.)
+
+.. code-block:: bash
+
+    sudo pip3 install ocrmypdf
+
+At your option, you may upgrade Ubuntu 16.04 LTS to Tesseract 4.0 for improved OCR results.
+
+.. code-block:: bash
+
+    sudo apt-get install -y software-properties-common python-software-properties
+    sudo add-apt-repository ppa:alex-p/tesseract-ocr -y
+    sudo apt-get update
+    sudo apt-get upgrade tesseract-ocr
+
+To add JBIG2 encoding, see `Installing the JBIG2 encoder`_.
+
+Ubuntu 14.04 LTS
+^^^^^^^^^^^^^^^^
+
+Installing on Ubuntu 14.04 LTS (trusty) is more difficult than some other options, because it is older and does not provide ``pip``.
+
+Update apt-get:
+
+.. code-block:: bash
+
+    sudo apt-get update
+
+Install system dependencies:
+
+.. code-block:: bash
+
+    sudo apt-get install \
+        software-properties-common python-software-properties \
+        zlib1g-dev \
+        libexempi3 \
+        libjpeg-dev \
+        libffi-dev \
+        pngquant \
+        qpdf
+
+We will need backports of Ghostscript 9.16, libav-11 (for unpaper 6.1), Tesseract 4.00 (alpha), and Python 3.6. This will replace Ghostscript and Tesseract 3.x on your system. Python 3.6 will be installed alongside the system Python 3.4.
+
+If you prefer to not modify your system in this matter, consider using a Docker container.
+
+.. code-block:: bash
+
+    sudo add-apt-repository ppa:vshn/ghostscript -y
+    sudo add-apt-repository ppa:heyarje/libav-11 -y

+        tesseract-ocr-eng \
+        libavformat56 libavcodec56 libavutil54 \

+    pip3.6 install ocrmypdf
+
+The ``wget`` command will download a program and run it.
+
+These installation instructions omit the optional dependency ``unpaper``, which is only available at version 0.4.2 in Ubuntu 14.04. The author could not find a backport of ``unpaper``, and created a .deb package to do the job of installing unpaper 6.1 (for x86 64-bit only):

We support rare image formats like non-monochrome 1-bit images. Thanks to pikepdf and QPDF, we auto-repair PDFs that are damaged. (Not that you need to know what any of these are! You should be able to throw any PDF at it.)

 * It is not always good at analyzing the natural reading order of documents. For example, it may fail to recognize that a document contains two columns and join text across the columns.
 * Poor quality scans may produce poor quality OCR. Garbage in, garbage out.

@@ -91,9 +90,11 @@ Ghostscript also imposes some limitations:
 * PDFs containing JBIG2-encoded content will be converted to CCITT Group4 encoding, which has lower compression ratios, if Ghostscript PDF/A is enabled.
 * PDFs containing JPEG 2000-encoded content will be converted to JPEG encoding, which may introduce compression artifacts, if Ghostscript PDF/A is enabled.
 * Ghostscript may transcode grayscale and color images, either lossy to lossless or lossless to lossy, based on an internal algorithm. This behavior can be suppressed by setting ``--pdfa-image-compression`` to ``jpeg`` or ``lossless`` to set all images to one type or the other. Ghostscript has no option to maintain the input image's format.

-OCRmyPDF is currently not designed to be used as a Python API; it is designed to be run as a command line tool. ``import ocrmypf`` currently attempts to process the command line on ``sys.argv`` at import time so it has side effects that will interfere with its use as a package. The API it presents should not be considered stable.
 
+Regarding OCRmyPDF itself:
+
+* PDFs that use transparency are not currently represented in the test suite
+* The Python API exported by ``import ocrmypdf`` is design to help scripts that use OCRmyPDF but is not currently capable of running OCRmyPDF jobs due to limitations in an underlying library.

+Installing the JBIG2 encoder
+==========================
+
+Most Linux distributions do not include a JBIG2 encoder since JBIG2 encoding was patented for a long time. All known JBIG2 US patents have expired as of 2017, but it is possible that unknown patents exist.
+
+JBIG2 encoding is recommended for OCRmyPDF and is used to losslessly create smaller PDFs. If JBIG2 encoding not available, lower quality encodings will be used.
+
+JBIG2 decoding is not patented and is performed automatically by most PDF viewers. It is widely supported has been part of the PDF specification since 2001.
+
+On macOS, Homebrew packages jbig2enc and OCRmyPDF includes it by default. The Docker image for OCRmyPDF also builds its own JBIG2 encoder from source.
+
+For all other Linux, you must build a JBIG2 encoder from source:
+
+.. code-block:: bash
+
+    git clone https://github.com/agl/jbig2enc
+    cd jbig2enc
+    ./autogen.sh
+    ./configure && make

-As of v4.2, users of ocrmypdf working languages outside the Latin alphabet should use the following syntax:
-
-.. code-block:: bash
-
-	ocrmypdf -l eng+gre --output-type pdf --pdf-renderer tesseract
-
-The reasons for this are:
-
-* The latest version of Ghostscript (9.19 as of this writing) has unfixed bugs in Unicode handling that generate invalid character maps, so Ghostscript cannot be used for PDF/A conversion
-* The default "hocr" PDF renderer does not handle Asian fonts properly

 Release notes
 =============
 
-OCRmyPDF uses `semantic versioning <http://semver.org/>`_ for its command line interface.
+OCRmyPDF uses `semantic versioning <http://semver.org/>`_ for its command line interface and its public API.
 
-The OCRmyPDF package itself does not contain a public API, although it is fairly stable and breaking changes are usually timed with a major release. A future release will clearly define the stable public API.
+The ``ocrmypdf`` package may now be imported. The public API may be useful in scripts that launch OCRmyPDF processes or that wish to use some of its features for working with PDFs.
+
+Unfortunately, the public API does **not** expose the ability to actually OCR a PDF. This is due to a limitation in an underlying library (ruffus) that makes OCRmyPDF non-reentrant.
+
+Note that it is licensed under GPLv3, so scripts that ``import ocrmypdf`` and are released publicly should probably also be licensed under GPLv3.

+v7.0.4
+------
+
+-   Fix exception thrown when trying to optimize a certain type of PNG embedded
+in a PDF with the ``-O2``

+image types that were previously excluded from optimization (CMYK and grayscale).
+Fixes `#285 <https://github.com/jbarlow83/OCRmyPDF/issues/285>`_.
+
+v7.0.3

+
+-   Fix issue `#284 <https://github.com/jbarlow83/OCRmyPDF/issues/284>`_, an error when parsing inline images that have are also image masks, by upgrading pikepdf to 0.3.1
+
+v7.0.2
+------
+
+-   Fix a regression with ``--rotate-pages`` on pages that already had rotations applied. (`#279 <https://github.com/jbarlow83/OCRmyPDF/issues/279>`_)
+
+-   Improve quality of page rotation in some cases by rasterizing a higher quality preview image. (`#281 <https://github.com/jbarlow83/OCRmyPDF/issues/281>`_)
+
+v7.0.1
+------
+
+-   Fix compatibility with img2pdf >= 0.3.0 by rejecting input images that have an alpha channel
+
+-   Add forward compatibility for pikepdf 0.3.0 (unrelated to img2pdf)
+
+-   Various documentation updates for v7.0.0 changes
+
+v7.0.0
+------
+
+-   The core algorithm for combining OCR layers with existing PDF pages has been rewritten and improved considerably.  PDFs are no longer split into single page PDFs for processing; instead, images are rendered and the OCR results are grafted onto the input PDF.  The new algorithm uses less temporary disk space and is much more performant especially for large files.
+
+-   New dependency: `pikepdf <https://github.com/pikepdf/pikepdf>`_. pikepdf is a powerful new Python PDF library driving the latest OCRmyPDF features, built on the QPDF C++ library (libqpdf).
+
+-   New feature: PDF optimization with ``-O`` or ``--optimize``.  After OCR, OCRmyPDF will perform image optimizations relevant to OCR PDFs.
+
+    +   If a JBIG2 encoder is available, then monochrome images will be converted, with the potential for huge savings on large black and white images, since JBIG2 is far more efficient than any other monochrome (bi-level) compression. (All known US patents related to JBIG2 have probably expired, but it remains the responsibility of the user to supply a JBIG2 encoder such as `jbig2enc <https://github.com/agl/jbig2enc>`_. OCRmyPDF does not implement JBIG2 encoding.)
+
+    +   If ``pngquant`` is installed, OCRmyPDF will optionally use it to perform lossy quantization and compression of PNG images.
+
+    +   The quality of JPEGs can also be lowered, on the assumption that a lower quality image may be suitable for storage after OCR.
+
+    +   This image optimization component will eventually be offered as an independent command line utility.
+
+    +   Optimization ranges from ``-O0`` through ``-O3``, where ``0`` disables optimization and ``3`` implements all options. ``1``, the default, performs only safe and lossless optimizations. (This is similar to GCC's optimization parameter.) The exact type of optimizations performed will vary over time.
+
+-   Small amounts of text in the margins of a page, such as watermarks, page numbers, or digital stamps, will no longer prevent the rest of a page from being OCRed when ``--skip-text`` is issued. This behavior is based on a heuristic.
+
+-   Removed features
+
+    +   The deprecated ``--pdf-renderer tesseract`` PDF renderer was removed.
+
+    +   ``-g``, the option to generate debug text pages, was removed because it was a maintenance burden and only worked in isolated cases. HOCR pages can still be previewed by running the hocrtransform.py with appropriate settings.
+
+-   Removed dependencies
+
+    +   ``PyPDF2``
+
+    +   ``defusedxml``
+
+    +   ``PyMuPDF``
+
+-   The ``sandwich`` PDF renderer can be used with all supported versions of Tesseract, including that those prior to v3.05 which don't support ``-c textonly``. (Tesseract v4.0.0 is recommended and more efficient.)
+
+-   ``--pdf-renderer auto`` option and the diagnostics used to select a PDF renderer now work better with old versions, but may make different decisions than past versions.
+
+-   If everything succeeds but PDF/A conversion fails, a distinct return code is now returned (``ExitCode.pdfa_conversion_failed (10)``) where this situation previously returned ``ExitCode.invalid_output_pdf (4)``. The latter is now returned only if there is some indication that the output file is invalid.
+
+-   Notes for downstream packagers
+
+    +   There is also a new dependency on ``python-xmp-toolkit`` which in turn depends on ``libexempi3``.
+
+    +   It may be necessary to separately ``pip install pycparser`` to avoid `another Python 3.7 issue <https://github.com/eliben/pycparser/pull/135>`_.

-OCRmyPDF must open and interpret your PDF in order to insert an OCR layer. First, it runs all PDFs through `qpdf <https://github.com/qpdf/qpdf>`_, a program that repairs PDFs with syntax errors.

-The LinnSequencer
-32 Track MIDI Sequence Recorder
-
-The LinnSequencer is a state-of-the-art composition and performance tool for the professional musician. It is
-
-extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
-
-¢ Operation is similar to multi-track tape recorder with PLAY, STOP, RECORD, FAST
-FORWARD, REWIND, and LOCATE controls.
-
-e Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
-be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
-
-synthesizers!
-
-¢ Ultra-fast 3%” disk drive stores complex songs in seconds and holds over 110,000 notes
-
-per disk!
-
-¢ One or all tracks may be TRANSPOSED at the touch of a key.
-e Exclusive real-time ERASE function makes editing FAST.
-* Exclusive REPEAT function automatically repeats any held notes at a pre-selected
-
-rhythmic value.
-
-¢ TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
-
-¢ Optional SMPTE time code synchronization.
-
-© Optional remote control.
-
-Recording a Sequence
-
-To record a sequence, simply press RECORD and PLAY,
-then play your MIDI keyboard in time to the Sequencer’s
-click track. When the sequence loops back around to bar 1,
-you’ ll hear what you played—only all timing errors will be
-
-corrected! (Timing correction may be adjusted or defeated).
-
-Any additional notes played will be added into the track
-— existing notes are not erased while recording!
-
-FAST FORWARD, REWIND, and LOCATE controls
-may be used at any time to quickly access any location in
-your sequence for spot-recording. To overdub a new part,
-select a different track and start recording—while you
-record, the first track will play in perfect sync (unless you
-MUTE it, or SOLO another track). In this way, up to 32
-tracks may be overdubbed! All MIDI effects are recorded
-including pitch bend, modulation, velocity, aftertouch,
-sustain pedal, and program changes!
-
-Editing
-
-To erase a wrong note, simply hold ERASE and press
-the note to be erased just before it plays in the sequence—
-when played back, it will be gone. Notes may also be
-
-added, erased, or changed using the SINGLE STEP func-
-tion. To overdub notes at specific points within a sequence,
-
-Additional Features
-
-simply use LOCATE, FAST FORWARD, or REWIND to
-find the desired bar number, then start recording.
-
-The INSERT/COPY function allows you to move bars
-from one location to another—in the same sequence or a
-different one. For example, you might insert a copy of the
-first verse between the second chorus and the bridge.
-DELETE BARS operates the same way to remove
-unwanted sections,
-
-Creating a Song
-
-One way to create a song is to record each track all the
-way through (up to 999 bars). Another way is to record
-each basic section (verse, chorus, etc.) in individual
-sequences, then use the CREATE SONG function to “chain”
-them together. CREATE SONG will then automatically
-copy all the parts into a new sequence. If desired, you can
-even set the last few bars to repeat infinitely, for a fadeout.
-
-Composition Without Compromise
-
-The technology you use should never be so complex that
-it interferes with the creative process. That’s precisely why
-the LinnSequencer is designed to let you compose, record
-and edit while devoting your undivided attention to your
-music. See your Linn dealer today for a demonstration!
-
-* Simple, easy to learn operation—the 32 character LCD display clearly guides you through all operations. If needed, the
-
-HELP button displays additional explanations.
-
-* Non-destructive recording—existing notes are not erased while recording.
-¢ Two FOOTSWITCH INPUTS may be assigned to remotely control many of the commonly used functions, including
-
-ERASE, REPEAT, PLAY/STOP, or LOCATE.
-
-¢ Iwo TRIGGER OUTPUTS may be programmed to output pulses at any selected note value.
-
-© Will sync to standard LinnDrum or Linn 9000 sync tone.
-
-© Utilizes ultra high-speed, 8 MHz 80186 16 bit computer internally for FAST operation.
-* TEMPO may be specified in BEATS-PER-MINUTE or FRAMES-PER-BEAT at 24, 25, or 30 frames per second,
-
-(even drop frame!)
-
-¢ TEMPO may be entered numerically, adjustable in tenths of a Beat-Per-Minute increments, or by tapping quarter notes
-
-on the TAP TEMPO button.
-
-¢ TEMPO CHANGES may be programmed into a sequence, with smooth transitions if desired.
-¢ Any TIME SIGNATURE may be used, and may be changed within a song.

+The LinnSequencer
+32 Track MIDI Sequence Recorder
+
+The LinnSequencer is a state—of—the-art composition and performance tool for the professional musician. It is
+
+extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
+
+0 Operation is similar to multi—track tape recorder with PLAY, STOP, RECORD, FAST
+FORWARD, REWIND, and LOCATE controls.
+
+0 Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
+be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
+
+synthesizers !
+
+0 Ultra—fast 3 1/2 ” disk drive stores complex songs in seconds and holds over 110,000 notes
+
+per disk!
+
+0 One or all tracks may be TRANSPOSED at the touch of a key.
+0 Exclusive real—time ERASE function makes editing FAST.
+0 Exclusive REPEAT function automatically repeats any held notes at a pre-selected
+
+rhythmic value.
+
+0 TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
+
+0 Optional SMPTE time code synchronization.
+
+0 Optional remote control.
+
+Recording 3 Sequence
+
+To record a sequence, simply press RECORD and PLAY,
+then play your MIDI keyboard in time to the Sequencer’s
+click track. When the sequence loops back around to bar 1,
+you’ll hear what you played—only all timing errors will be
+
+corrected! (Timing correction may be adjusted or defeated).
+
+Any additional notes played will be added into the track
+—existing notes are not erased while recording!
+
+FAST FORWARD, REWIND, and LOCATE controls
+may be used at any time to quickly access any location in
+your sequence for spot—recording. To overdub a new part,
+select a different track and start recording~while you
+record, the first‘track will play in perfect sync (unless you
+MUTE it, or SOLO another track). In this way, up to 32
+tracks may be overdubbed! All MIDI effects are recorded
+including pitch bend, modulation, velocity, aftertouch,
+sustain pedal, and program changes!
+
+Editing
+
+To erase a wrong note, simply hold ERASE and press
+the note to be erased just before it plays in the sequence—
+when played back, it will be gone. Notes may also be

+The LinnSequencer
+32 Track MIDI Sequence Recorder
+
+The LinnSequencer is a state—of—the-art composition and performance tool for the professional musician. It is
+
+extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
+
+0 Operation is similar to multi—track tape recorder with PLAY, STOP, RECORD, FAST
+FORWARD, REWIND, and LOCATE controls.
+
+0 Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
+be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
+
+synthesizers !
+
+0 Ultra—fast 3 1/2 ” disk drive stores complex songs in seconds and holds over 110,000 notes
+
+per disk!
+
+0 One or all tracks may be TRANSPOSED at the touch of a key.
+0 Exclusive real—time ERASE function makes editing FAST.
+0 Exclusive REPEAT function automatically repeats any held notes at a pre-selected
+
+rhythmic value.
+
+0 TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
+
+0 Optional SMPTE time code synchronization.
+
+0 Optional remote control.
+
+Recording 3 Sequence
+
+To record a sequence, simply press RECORD and PLAY,
+then play your MIDI keyboard in time to the Sequencer’s
+click track. When the sequence loops back around to bar 1,
+you’ll hear what you played—only all timing errors will be
+
+corrected! (Timing correction may be adjusted or defeated).
+
+Any additional notes played will be added into the track
+—existing notes are not erased while recording!
+
+FAST FORWARD, REWIND, and LOCATE controls
+may be used at any time to quickly access any location in
+your sequence for spot—recording. To overdub a new part,
+select a different track and start recording~while you
+record, the first‘track will play in perfect sync (unless you
+MUTE it, or SOLO another track). In this way, up to 32
+tracks may be overdubbed! All MIDI effects are recorded
+including pitch bend, modulation, velocity, aftertouch,
+sustain pedal, and program changes!
+
+Editing
+
+To erase a wrong note, simply hold ERASE and press
+the note to be erased just before it plays in the sequence—
+when played back, it will be gone. Notes may also be
+
+added, erased, or changed using the SINGLE STEP func-
+tion. To overdub notes at specific points within a sequence,
+

+The LinnSequencer
+32 Track MIDI Sequence Recorder
+
+The LinnSequencer is a state—of—the-art composition and performance tool for the professional musician. It is
+
+extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
+
+0 Operation is similar to multi—track tape recorder with PLAY, STOP, RECORD, FAST
+FORWARD, REWIND, and LOCATE controls.
+
+0 Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
+be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
+
+synthesizers !
+
+0 Ultra—fast 3 1/2 ” disk drive stores complex songs in seconds and holds over 110,000 notes
+
+per disk!
+
+0 One or all tracks may be TRANSPOSED at the touch of a key.
+0 Exclusive real—time ERASE function makes editing FAST.
+0 Exclusive REPEAT function automatically repeats any held notes at a pre-selected
+
+rhythmic value.
+
+0 TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
+
+0 Optional SMPTE time code synchronization.
+
+0 Optional remote control.
+
+Recording 3 Sequence
+
+To record a sequence, simply press RECORD and PLAY,
+then play your MIDI keyboard in time to the Sequencer’s
+click track. When the sequence loops back around to bar 1,
+you’ll hear what you played—only all timing errors will be
+
+corrected! (Timing correction may be adjusted or defeated).
+
+Any additional notes played will be added into the track
+—existing notes are not erased while recording!
+
+FAST FORWARD, REWIND, and LOCATE controls
+may be used at any time to quickly access any location in
+your sequence for spot—recording. To overdub a new part,
+select a different track and start recording~while you
+record, the first‘track will play in perfect sync (unless you
+MUTE it, or SOLO another track). In this way, up to 32
+tracks may be overdubbed! All MIDI effects are recorded
+including pitch bend, modulation, velocity, aftertouch,
+sustain pedal, and program changes!
+
+Editing
+
+To erase a wrong note, simply hold ERASE and press
+the note to be erased just before it plays in the sequence—
+when played back, it will be gone. Notes may also be

+The LinnSequencer
+32 Track MIDI Sequence Recorder
+
+The LinnSequencer is a state—of—the-art composition and performance tool for the professional musician. It is
+
+extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
+
+0 Operation is similar to multi—track tape recorder with PLAY, STOP, RECORD, FAST
+FORWARD, REWIND, and LOCATE controls.
+
+0 Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
+be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
+
+synthesizers !
+
+0 Ultra—fast 3 1/2 ” disk drive stores complex songs in seconds and holds over 110,000 notes
+
+per disk!
+
+0 One or all tracks may be TRANSPOSED at the touch of a key.
+0 Exclusive real—time ERASE function makes editing FAST.
+0 Exclusive REPEAT function automatically repeats any held notes at a pre-selected
+
+rhythmic value.
+
+0 TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
+
+0 Optional SMPTE time code synchronization.
+
+0 Optional remote control.
+
+Recording 3 Sequence
+
+To record a sequence, simply press RECORD and PLAY,
+then play your MIDI keyboard in time to the Sequencer’s
+click track. When the sequence loops back around to bar 1,
+you’ll hear what you played—only all timing errors will be
+
+corrected! (Timing correction may be adjusted or defeated).
+
+Any additional notes played will be added into the track
+—existing notes are not erased while recording!
+
+FAST FORWARD, REWIND, and LOCATE controls
+may be used at any time to quickly access any location in
+your sequence for spot—recording. To overdub a new part,
+select a different track and start recording~while you
+record, the first‘track will play in perfect sync (unless you
+MUTE it, or SOLO another track). In this way, up to 32
+tracks may be overdubbed! All MIDI effects are recorded
+including pitch bend, modulation, velocity, aftertouch,
+sustain pedal, and program changes!
+
+Editing
+
+To erase a wrong note, simply hold ERASE and press
+the note to be erased just before it plays in the sequence—
+when played back, it will be gone. Notes may also be
+
+added, erased, or changed using the SINGLE STEP func-
+tion. To overdub notes at specific points within a sequence,
+

+The LinnSequencer
+32 Track MIDI Sequence Recorder
+
+The LinnSequencer is a state—of—the-art composition and performance tool for the professional musician. It is
+
+extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
+
+0 Operation is similar to multi—track tape recorder with PLAY, STOP, RECORD, FAST
+FORWARD, REWIND, and LOCATE controls.
+
+0 Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
+be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
+
+synthesizers !
+
+0 Ultra—fast 3 1/2 ” disk drive stores complex songs in seconds and holds over 110,000 notes
+
+per disk!
+
+0 One or all tracks may be TRANSPOSED at the touch of a key.
+0 Exclusive real—time ERASE function makes editing FAST.
+0 Exclusive REPEAT function automatically repeats any held notes at a pre-selected
+
+rhythmic value.
+
+0 TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
+
+0 Optional SMPTE time code synchronization.
+
+0 Optional remote control.
+
+Recording 3 Sequence
+
+To record a sequence, simply press RECORD and PLAY,
+then play your MIDI keyboard in time to the Sequencer’s
+click track. When the sequence loops back around to bar 1,
+you’ll hear what you played—only all timing errors will be
+
+corrected! (Timing correction may be adjusted or defeated).
+
+Any additional notes played will be added into the track
+—existing notes are not erased while recording!
+
+FAST FORWARD, REWIND, and LOCATE controls
+may be used at any time to quickly access any location in
+your sequence for spot—recording. To overdub a new part,
+select a different track and start recording~while you
+record, the first‘track will play in perfect sync (unless you
+MUTE it, or SOLO another track). In this way, up to 32
+tracks may be overdubbed! All MIDI effects are recorded
+including pitch bend, modulation, velocity, aftertouch,
+sustain pedal, and program changes!
+
+Editing
+
+To erase a wrong note, simply hold ERASE and press
+the note to be erased just before it plays in the sequence—
+when played back, it will be gone. Notes may also be

+The LinnSequencer
+32 Track MIDI Sequence Recorder
+
+The LinnSequencer is a state—of—the-art composition and performance tool for the professional musician. It is
+
+extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
+
+0 Operation is similar to multi—track tape recorder with PLAY, STOP, RECORD, FAST
+FORWARD, REWIND, and LOCATE controls.
+
+0 Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
+be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
+
+synthesizers !
+
+0 Ultra—fast 3 1/2 ” disk drive stores complex songs in seconds and holds over 110,000 notes
+
+per disk!
+
+0 One or all tracks may be TRANSPOSED at the touch of a key.
+0 Exclusive real—time ERASE function makes editing FAST.
+0 Exclusive REPEAT function automatically repeats any held notes at a pre-selected
+
+rhythmic value.
+
+0 TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
+
+0 Optional SMPTE time code synchronization.
+
+0 Optional remote control.
+
+Recording 3 Sequence
+
+To record a sequence, simply press RECORD and PLAY,
+then play your MIDI keyboard in time to the Sequencer’s
+click track. When the sequence loops back around to bar 1,
+you’ll hear what you played—only all timing errors will be
+
+corrected! (Timing correction may be adjusted or defeated).
+
+Any additional notes played will be added into the track
+—existing notes are not erased while recording!
+
+FAST FORWARD, REWIND, and LOCATE controls
+may be used at any time to quickly access any location in
+your sequence for spot—recording. To overdub a new part,
+select a different track and start recording~while you
+record, the first‘track will play in perfect sync (unless you
+MUTE it, or SOLO another track). In this way, up to 32
+tracks may be overdubbed! All MIDI effects are recorded
+including pitch bend, modulation, velocity, aftertouch,
+sustain pedal, and program changes!
+
+Editing
+
+To erase a wrong note, simply hold ERASE and press
+the note to be erased just before it plays in the sequence—
+when played back, it will be gone. Notes may also be
+
+added, erased, or changed using the SINGLE STEP func-
+tion. To overdub notes at specific points within a sequence,
+

+The LinnSequencer
+32 Track MIDI Sequence Recorder
+
+The LinnSequencer is a state—of—the-art composition and performance tool for the professional musician. It is
+
+extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
+
+0 Operation is similar to multi—track tape recorder with PLAY, STOP, RECORD, FAST
+FORWARD, REWIND, and LOCATE controls.
+
+0 Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
+be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
+
+synthesizers !
+
+0 Ultra—fast 3 1/2 ” disk drive stores complex songs in seconds and holds over 110,000 notes
+
+per disk!
+
+0 One or all tracks may be TRANSPOSED at the touch of a key.
+0 Exclusive real—time ERASE function makes editing FAST.
+0 Exclusive REPEAT function automatically repeats any held notes at a pre-selected
+
+rhythmic value.
+
+0 TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
+
+0 Optional SMPTE time code synchronization.
+
+0 Optional remote control.
+
+Recording 3 Sequence
+
+To record a sequence, simply press RECORD and PLAY,
+then play your MIDI keyboard in time to the Sequencer’s
+click track. When the sequence loops back around to bar 1,
+you’ll hear what you played—only all timing errors will be
+
+corrected! (Timing correction may be adjusted or defeated).
+
+Any additional notes played will be added into the track
+—existing notes are not erased while recording!
+
+FAST FORWARD, REWIND, and LOCATE controls
+may be used at any time to quickly access any location in
+your sequence for spot—recording. To overdub a new part,
+select a different track and start recording~while you
+record, the first‘track will play in perfect sync (unless you
+MUTE it, or SOLO another track). In this way, up to 32
+tracks may be overdubbed! All MIDI effects are recorded
+including pitch bend, modulation, velocity, aftertouch,
+sustain pedal, and program changes!
+
+Editing
+
+To erase a wrong note, simply hold ERASE and press
+the note to be erased just before it plays in the sequence—
+when played back, it will be gone. Notes may also be

-The LinnSequencer
-32 Track MIDI Sequence Recorder
-
-The LinnSequencer is a state-of-the-art composition and performance tool for the professional musician. It is
-
-extremely powerful, yet amazingly simple to learn and use. It’s many remarkable features include:
-
-¢ Operation is similar to multi-track tape recorder with PLAY, STOP, RECORD, FAST
-FORWARD, REWIND, and LOCATE controls.
-
-e Each of the 100 sequences contains 32 simultaneous, polyphonic tracks. Each track may
-be assigned to one of 16 MIDI channels. Simultaneously plays up to 16 polyphonic
-
-synthesizers!
-
-¢ Ultra-fast 3%” disk drive stores complex songs in seconds and holds over 110,000 notes
-
-per disk!
-
-¢ One or all tracks may be TRANSPOSED at the touch of a key.
-e Exclusive real-time ERASE function makes editing FAST.
-* Exclusive REPEAT function automatically repeats any held notes at a pre-selected
-
-rhythmic value.
-
-¢ TIMING CORRECTION works during playback and operates without ‘chopping’ notes.
-
-¢ Optional SMPTE time code synchronization.
-
-© Optional remote control.
-
-Recording a Sequence
-
-To record a sequence, simply press RECORD and PLAY,
-then play your MIDI keyboard in time to the Sequencer’s
-click track. When the sequence loops back around to bar 1,
-you’ ll hear what you played—only all timing errors will be
-
-corrected! (Timing correction may be adjusted or defeated).
-
-Any additional notes played will be added into the track
-— existing notes are not erased while recording!
-
-FAST FORWARD, REWIND, and LOCATE controls
-may be used at any time to quickly access any location in
-your sequence for spot-recording. To overdub a new part,
-select a different track and start recording—while you
-record, the first track will play in perfect sync (unless you
-MUTE it, or SOLO another track). In this way, up to 32
-tracks may be overdubbed! All MIDI effects are recorded
-including pitch bend, modulation, velocity, aftertouch,
-sustain pedal, and program changes!
-
-Editing
-
-To erase a wrong note, simply hold ERASE and press
-the note to be erased just before it plays in the sequence—
-when played back, it will be gone. Notes may also be
-
-added, erased, or changed using the SINGLE STEP func-
-tion. To overdub notes at specific points within a sequence,
