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
sync’d to 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.

on how trapezoids are set up.
r.dn 0–100 Ramp down: only available for trapezoid.
PhA 0–63
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.
