P 31 LFO waveshape (default :TR)
- Sets the LFO waveshape. All waveshapes modulate CV and/or Aux any value between 0 to a positive
value, except triangle, which modulates positive and negative. The following may be selected: (the
downward arrow (↓) indicates the default trigger point when in MIDI sync mode). Note that the sync
point can be changed using parameter #33 – LFO Sync Start Point.

P 32 LFO MIDI SYNC (default: oFF)
Range, off [oFF], 1 to 96
- Allows the LFO waveform to be synchronised to MIDI clock, with a variable divide ratio. The LFO
waveform will automatically adjust its length so that it will start at the beginning of a bar, and last for
whatever musical time it is set for (see below for divide ratios).
A divide ratio can be set, so the LFO only re-triggers every so many MIDI clock messages. MIDI sends
24 clocks per quarter note. So if divide is set to 1, there will be 1 cycle of the LFO for every 1 MIDI
clock. (i.e. 24 cycles per quarter note). If set to 24, there will be 1 cycle of the LFO for every 24 MIDI
clocks. (i.e. 1 cycle of the LFO per quarter note).
Below is a table of values you can set the divide ratio to obtain LFO cycles of various musical lengths:
Note type: Divide ratio:
Semibreve 96
Minim 48
Crotchets 24
Crotchet triplets 16
Quavers 12
Quaver triplets 8
Semiquavers 6
Semiquaver triplets 4
Demisemiquavers 3
Demisemiquaver triplets 2
Do not use low divide ratios at high clock speeds (particularly 1).
P 33 LFO Sync Start Point (default :0)
Range 0 to 255
- Sets where the waveform will start when MIDI sync is active or Key-On reset is on.
P 34 Key-On resets LFO Wave (default :off)
The following can be selected:
Off [oFF]
On [ on]
- When on, the LFO waveform is reset to the selected start point whenever a new note is played.
