LFO Waveforms
SHORT PRESS cycles between:
Triangle
Square
Ramp
Random (Sample & Hold)
Super Triangle
Super Square
Super Ramp
Super Random
The “Super” version of each waveform has 4 additional
LFOs superimposed onto the original LFO waveform.
LONG PRESS turns on LFO SYNC - this synchronizes the LFO
to the Delay Time as set by the delay time knob, tap tempo
or MIDI beat clock. When LFO Sync is turned on, the LFO
SPEED knob determines the LFO Speed to Delay Time ratio
with minimum being 1:4 and maximum being 4:1 for six
possible values (1:4, 1:3, 1:2, 2:1, 3:1, 4:1)
