seq
Description
seq is a sequencer of raw MIDI bytes. You can control the speed of playback (only at the time you start it), read and write from files, and record from live MIDI input. See also midiparse and midiformat which you may need to get to and from raw MIDI.

Arguments
filename [symbol]
Specifies the name of a file to be read into seq automatically when the patch is loaded.
Attributes
overridetempo [int] (default: 0)
If enabled (default = tempo attribute will override any tempo requested by the sequence. In this case, tempo attribute will not be updated when a new file is read, nor when tempo meta messages appear in the sequence data. The meta messages will continue to be output from the right outlet of the seq object in this case.
(disabled)), the value of thesequencetempo [float]
The unmodified tempo of the sequence. This is a read-only value for convenience purposes.
tempo [float] (default: 120.)
If the seq has read a MIDI file with tempo information, the tempo attribute will reflect the current tempo at the current playback time. If the file has no tempo information, the default tempo is 120. (120 BPM). The tempo attribute can be modified to change the playback speed, but will be overwritten by tempo changes present in the MIDI file, and will be overwritten when a new MIDI file is read.
Common Box Attributes
annotation [symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.
background [int] (default: 0)
Adds or removes the object from the patcher's background layer.

hidden [int] (default: 0)
Toggles whether an object is hidden when the patcher is locked.
hint [symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick [int] (default: 0)
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile [symbol]
JS Painter File
patching_rect [4 floats] (default: 0. 0. 100. 0.)
Sets the position and size of the object in the patcher window.
position [2 floats]
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation [int] (default: 0)
Sets whether an object belongs to the patcher's presentation.
presentation_rect [4 floats] (default: 0. 0. 0. 0.)
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect [4 floats]
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size [2 floats]
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
textcolor [4 floats]
Sets the color for the object's text in RGBA format.
textjustification [int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'

Note: The seq object reads and writes both single track (format 0) and multi-track (format 1) standard MIDI files. It can also read and write text files in which each line consists of a start time in milliseconds (the time elapsed since the beginning of the sequence) followed by the (space-separated) bytes of a MIDI message recorded at that start time. For example,
0 144 60 112;
1000 144 60 0;
1500 192 31;
1500 144 60 112;
2500 144 60 0;
plays the note middle C on channel 1 for one second, then half a second later changes to program number 31 and plays middle C again for one second.

Out middle outlet: Indicates that seq has finished playing the current sequence. (The is sent out immediately before the final event of the sequence is played.)
int
Out left outlet: When seq is sent out the outlet in the form of individual MIDI bytes, usually to be sent to midiparse or midiout.
or is received in the inlet, the sequence stored inlist
Out right outlet: If the current sequence loaded by seq contains MIDI meta messages, these are sent from the right outlet, prepended with the word , followed by the name of the meta metssage and the data.
Known meta messages are: , , , , , , , , , , , , , , . Any other messages will be identified as . The text messages ( , , , , , , ) are converted to symbols. The meta message is displayed as a BPM value.
