SUBTRACTOR SYNTHESIZER
(RECORD+REASON)
548
Sync
By clicking this button you activate/deactivate LFO sync. The frequency of the LFO will then be synchronized to the
song tempo, in one of 16 possible time divisions. When sync is activated, the Rate knob (see below) is used for set-
ting the desired time division.
Turn the knob and check the tooltip for an indication of the time division.
Rate
The Rate knob controls the LFO’s frequency. Turn clockwise for a faster modulation rate.
Amount
This parameter determines to what degree the selected parameter destination will be affected by LFO 1. Raising this
knob’s value creates more drastic results.
LFO 2 Parameters
LFO 2 is polyphonic. This means that for every note you play, an independent LFO cycle is generated, whereas LFO
1 always modulates the destination parameter using the same “cycle”. This can be used to produce subtle cross-
modulation effects, with several LFO cycles that “beat” against each other. This also enables LFO 2 to produce mod-
ulation rates that vary across the keyboard (see the “Keyboard Tracking” parameter below).
Destination
The available LFO 2 Destinations are as follows:
LFO 2 Delay
This parameter is used to set a delay between when a note is played and when the LFO modulation “kicks in”. For ex-
ample, if Osc 1 & 2 is selected as the destination parameter and Delay was set to a moderate value, the sound would
start out unmodulated, with the vibrato only setting in if you hold the note(s) long enough. Delayed LFO modulation
can be very useful, especially if you are playing musical instrument-like sounds like violin or flute. Naturally it could
also be used to control more extreme modulation effects and still retain the “playability” of the sound.
LFO 2 Keyboard Tracking
If LFO keyboard tracking is activated, the LFO rate will progressively increase the higher up on the keyboard you play.
Raising this value creates more drastic results.

Description
Osc 1&2 Selecting this makes LFO 2 modulate the pitch (frequency) of Osc 1 and Osc 2.
Phase Selecting this makes the LFO 2 modulate the Phase Offset parameter for both Osc 1 and 2. Note that
Phase Offset Modulation (Subtraction or Multiplication) must be activated for this to have any effect.
Filter Freq 2 Selecting this makes the LFO 2 modulate the filter frequency for Filter 2.
Amp Selecting this makes the LFO 2 modulate the overall volume., to create tremolo-effects.
