Rate (LFO 1 and 2)
This knob controls the frequency of the LFO. For a faster modulation rate, turn the knob to the right. The Rate knob
of LFO 1 is also used for setting the timedivision when synchronizing the LFO to the song tempo (see below).
Delay (LFO 1 and 2)
This can be used for setting a delay between when a note is played and when the LFO modulation starts kicking in
(gradually). This way, you can make the sound start unmodulated, and then have the LFO modulation start after you
have kept the key(s) pressed down for a while.
Turn the knob to the right to increase the delay time.
Mode (LFO 1 only)
This lets you set the “operation mode” for the LFO. Click the button to switch between the available modes:
•Group Rate
In this mode, the LFO will run at the rate set for its group in the group section, rather than at the rate set here (see
“Group parameters”). This way, all zones in the group will have the exact same modulation rate.
• Tempo Sync
In this mode, the LFO will be synchronized to the song tempo, in one of 16 possible time divisions.
! When tempo sync is activated, the Rate knob is used for selecting the desired timedivision. Turn the Rate knob
and observe the tool tip for an indication of the timedivision.
•Free Run
In free run mode, the LFO simply runs at the rate set with the Rate parameter. Furthermore, if Key Sync is deacti-
vated, the modulation cycle will not be retriggered each time you press a key - it will run continuously.
Waveform (LFO 1 only)
Here, you select which type of waveform should be used for modulating the destination parameters.
Click the button to switch between the following waveforms:
! LFO 2 always uses a triangle waveform.
Key Sync (LFO 1 only)
By activating key sync, you “force” the LFO to restart its modulation cycle each time a key is pressed.
! Note that LFO 2 always uses Key Sync.

Description
Triangle This is a smooth waveform, suitable for normal vibrato.
Inverted Sawtooth This produces a “ramp up” cycle. If applied to an oscillator’s frequency, the pitch would sweep up,
after which the cycle immediately starts over.
Sawtooth This produces a “ramp down” cycle, the same as above but inverted.
Square This produces cycles that abruptly change between two values, usable for trills etc.
Random Produces random stepped modulation to the destination. Some vintage analog synths called this
feature “sample & hold”.
Soft Random The same as above, but with smooth modulation.
