LFO mode
In LFO mode, an internal low-frequency-oscillator ( LFO ) controls the filter cutoff. The speed of the LFO
can be controlled precisely and can even be synchronised with a sequencer using MIDI ( “ MIDI operation”
on page 25
). The following sub-parameters configure the LFO .

Type of LFO clock:
tempo in bpm
derived from filter 1’s
LFO (only available for filter 2)
pedal is used to tap a tempo
pedal controls max (bP.h) and min (bP.L) bpm

MIDI clock
bPM 10–999 Sets LFO tempo in bpm. Only available if tyP is set to tPo.
bP.h 10–999
bpm high: bpm when footpedal is in toe down position.
Only available when tyP is set to PEd. bpm is interpolated
between bpm-high and bpm-low depending on the
position of the footpedal.
bP.L 10–999
bpm low: bpm when footpedal is in heel down position.
Only available when tyP is set to PEd.

Phase: controls the phase of filter 2 relative to filter 1. Only
available when tyP is -F1,
i.e., filter 2 is sync’d to filter 1.
