LFO control
P 30
LFO rate / speed (default :116) [approx 6.25Hz]
- Sets the speed of the LFO. Range approx 0.1Hz to 100Hz.
Range
0 to 191
Note: This number is just a numeric value for reference purposes only. It is not calibrated in mS or any
other unit. The scale is roughly logarithmic. Approximately 0=0.1Hz 66=1Hz 129=10Hz 191=100Hz
P 31
LFO waveshape (default :TR)
- Sets the LFO waveshape. All waveshapes modulate CV and/or Aux1 any value between 0 to a
positive value, except triangle, which modulates positive and negative. The following may be selected:
(the downward arrow (

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

Crotchet triplets

Do not use low divide ratios at high clock speeds (particularly 1) and switch off if not using.
P 33
LFO Sync Start Point (default :0)
- Sets where the waveform will start when MIDI sync is active or Key-On reset is on.
Range
0 to 255
