MIDI control
Selection of SAW or SQUARE wave is done via Program Change, where Program 1 is SAW wave and Program 2 is SQUARE wave, then
sequentially repeats SAW wave as Program 3, SQUARE wave as Program 4 and so on until Program 128. The unit has two ways of
interpretation of received MIDI notes: SEQUENCER MODE and LIVE MODE. Interepretation mode is selected via jumper located on
connector labeled as “CH&MODE”, while reproduced notes are within range from MIDI note 24 to MIDI note 72 (C1 – C5). The unit
doesn't support MIDI pitch change control. Duration and level of envelope only affects the filter. In case that note has accent, then it also
affects the controlled amplifier.
SEQUENCER MODE
is mode in which the way of playing current note depends on the way the last note was played. The way of
playing the note is defined by it's velocity, which is shown in this table:
Velocity 0 = NOTE OFF . It has the same meaning as a standard MIDI message $80 note $00. This defines end of duration of
audibility (GATE) of the same note.
Velocity 1 - 16 = NOTE OFF. Note is being turned off, unless the previous note had a SLIDE function, in which case it lasts as long as the
GATE of the same note.
Velocity 17 - 32 = NOTE OFF + SLIDE. Similar to the previous case, but this time note stays on until the next note.
Velocity 33 - 48 = NOTE ON. Duration of the note is defined by the GATE. It turns the note on and triggers the envelope, but it is
applied only if the previous note doesn't have SLIDE turned on ( portamento, gradual slide from previous note to current note). If the
previous note had SLIDE turned on, then envelope wouldn't be triggered and only SLIDE effect would be executed. Duration of the
envelope is defined by MIDI command CC 57.
Velocity 49 - 64 = NOTE ON + SLIDE. Duration of the note is until next note and is not defined by GATE. It turns the note on and
triggers the envelope, but it is applied only if the previous note doesn't have the SLIDE turned on. If the previous note had the SLIDE
turned on, then envelope wouldn't be triggered and only the SLIDE effect would be executed. Duration of the envelope is defined by
MIDI command CC 57.
Velocity 65 - 80 = NOTE OFF + ACCENT. Same as NOTE OFF. Left for compatibility reasons.
Velocity 81 - 96 = NOTE OFF + SLIDE. Same as NOTE OFF + SLIDE. Left for compatibility reasons.
Velocity 97 – 112 = NOTE ON + ACCENT. Duration of the note is defined by the GATE. It turns the note on and triggers the
envelope, but it is applied only if the previous note doesn't have SLIDE turned on. If the previous note had SLIDE turned on, then
envelope wouldn't be triggered and only SLIDE effect would be executed. Duration of an envelope is a constant ~250mS. Value of
the accent is added to the level value of the note. Accent is defined by the MIDI command CC 58.
Velocity 113 - 127 = NOTE ON + SLIDE. Duration of the note is until next note and is not defined by the GATE. It turns
the note on and triggers the envelope, but it is applied only if the previous note doesn't have the SLIDE turned on. If the previous
note had SLIDE turned on, then envelope wouldn't be triggered and only SLIDE effect would be executed.Duration of the envelope
is a constant ~250mS. Value of the accent is added to the level value of the note. Accent is defined by the MIDI command CC 58.
