Like the COPY and ERASE buttons, the MIDI CHANNEL button is only active while it is held down. It is used to select the MIDI channel of a track or part (it has no function in SONG mode). When held down, track one's LED will light, and the display will show the MIDI channel selected for that track:


The keypad or +/- buttons can be used to change the selected track's MIDI channel, and other tracks can be displayed or changed by selecting the desired track button (only one track is lit at a time). The selection of the channel can be 0 (UNCHANGED), or 1 through 16. A given track always retains its recorded MIDI channel information, so that if a track contains notes from more than one channel, it can be played back as recorded. In this case, it is desired to assign the track to UNCHANGED, which means that it will output on the same MIDI channels as are recorded. Whenever a new track is recorded, it defaults to UNCHANGED. If a specific MIDI channel is selected (1-16). then the selected track's notes will all be output on the selected channel. However, the actual track information remains unchanged, so that returning a track to UNCHANGED will cause the separate MIDI channels to play back as before.

Note: An empty track can be assigned to a MIDI channel before recording onto it, which will cause that channel to be output while recording if MIDI ECHO is on. Also, if a track is copied to an empty track, its MIDI channel setting will be copied as well. If a track or part is erased, its MIDI channel assignment is left as it was.


The QUANTIZE button is used to correct the timing of notes to any desired beat value. QUANTIZE only moves note events, and does not alter controllers, pitch bend, after touch, program change, and system exclusive information. While holding down the QUANTIZE button in part mode, the most recently recorded track will be lit, and the display will read:


The 10 quantize choices are 1/2, 1/4, 1/6, 1/8, 1/12, 1/16, 1/24, 1/32, 1/48, 1/64. The +/- buttons or the keypad can be used to scroll through the choices. The keypad buttons 0-9 can also be used to select the quantize value directly, with 0=1/2 and 9=1/64. The track select buttons can be used to select the desired track(s) to be quantized. When QUANTIZE is first pressed, all eight track LEDs will be lit, indicating that all tracks will be quantized if RECORD is pressed. If a track button is pressed, all other tracks will turn off, and only that track will be selected. From that point on, each track select button will turn on or off its associated LED, so that any combination of tracks can be selected to be quantized. Pressing the RECORD button initiates the quantizing, and changes the display to:


This display remains until the RECORD button is released, which then returns the sequencer to its previous quantize display. The quantization process changes the start point of each note to the nearest quantize beat, but leaves the note release point where it was, which changes the actual note duration. Other quantizing options can be selected by using the page up and page down buttons. Pressing the page up button scrolls through the following choices:




If RECORD is pressed with QUANTIZE NOTE START & END being displayed, the release times of the notes will also be quantized to the selected quantize beat. If NOTE END is selected, only the release times of the notes will be quantized. If KEEP DURATION is selected, a note's duration will remain constant, i.e., if the start of a note is moved 1/16 note ahead, the release will also move 1/16 ahead.

In SONG mode, the QUANTIZE button is used to select an amount of clock offset for each track in a song. These offsets are global settings used by all songs, and do not affect the individual parts directly. The purpose of this feature is to allow the user to compensate for MIDI delays, and sound devices with slow attack times. While holding the QUANTIZE button in SONG mode, the first track LED will light, all others will be off, and the display will read as follows:


The value can be set from -48 to +48 384th notes (+/- 1/2 note) by using the keypad or the +/- buttons. Positive values represent a shift forward in time, and negative values represent a shift backward in time. When entering a value with the keypad, the sign remains unchanged (except when entering 00, which is always positive). To change the sign, the +/- keys must be used to "pass through" zero to the other side. Each track can be selected and set independently. Of course, the first beat of the first part of a song cannot be advanced (it can't read minds...).
