LFO 1
An LFO (Low Frequency Oscillator) is used for generating cyclic modulation. A typical example is to have an LFO
modulate the pitch of an oscillator to produce vibrato, but there are countless other applications for LFOs.
D LFO 1 will apply modulation polyphonically.
I.e. if LFO 1 modulation of a parameter is assigned, an individual LFO cycle will be triggered for each note you play.
D You select a LFO waveform by using the spin controls beside the waveform display, or by clicking in the dis-
play and moving the mouse up or down.
The following parameters are available for LFO 1:

Description
Rate This sets the frequency or rate of the LFO.
Waveform This sets the LFO waveform. Apart from standard waveforms (sine, square etc.) there are various
different random, non-linear and stepped waveforms. The shape of the waveforms are shown in
the display, and these shapes basically reflect how a signal is affected.
Delay This introduces a delay before the LFO modulation onset after a note is played. Turn clockwise for
longer delay.
KBD Follow This determines if (or how much) the Rate parameter is affected by note pitch. If you turn the knob
clockwise, the modulation rate will increase the higher up on the keyboard you play.
Key Sync As explained previously, LFO 1 is polyphonic and will produce a separate LFO cycle for each note
played. If Key Sync is off, the cycles are free running, meaning that when you play a note the mod-
ulation may start anywhere in the LFO waveform cycle. If Key Sync is on, the LFO cycles are reset
for each note played.
Tempo sync If this is on, the Rate will be synced to the sequencer tempo.
