SUBTRACTOR SYNTHESIZER

196

Destination

The available LFO 1 Destinations are as follows:

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 setting the desired ti-

medivision.

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 cy-

cle 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 pro-

duce modulation 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 example, if Osc 1 & 2 is selected as the destination pa-

rameter and Delay was set to a moderate value, the sound would start out unmodu-

lated, 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 mod-

ulation 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.

✪ If the LFO is set to modulate the phase offset, LFO keyboard tracking can

produce good results. For example, synth string pads and other sounds

that use PWM (see page 189) can benefit from this.

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 2. Raising this knob’s value creates more drastic results.

Destination

Description

Osc 1&2 Selecting this makes LFO 1 control the pitch (frequency) of Osc 1

and Osc 2.

Osc 2 Same as above, but for Osc 2.

Filter Freq Selecting this makes the LFO 1 control the filter frequency for Filter

1 (and Filter 2 if linked).

FM Selecting this makes the LFO 1 control the FM Amount parameter.

Both oscillators must be activated for this to have any effect.

Phase Selecting this makes the LFO 1 control the Phase Offset parameter

for both Osc 1 and 2. Note that Phase Offset Modulation (Subtrac-

tion or Multiplication) must be activated for this to have any effect

(see page 189).

Osc Mix Selecting this makes the LFO 1 control the oscillator Mix parameter.

Destination

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 parame-

ter for both Osc 1 and 2. Note that Phase Offset Modulation (Sub-

traction or Multiplication) must be activated for this to have any effect

(see page 189).

Filter Freq 2 Selecting this makes the LFO 2 modulate the filter frequency for Fil-

ter 2.

Amp Selecting this makes the LFO 2 modulate the overall volume., to cre-

ate tremolo-effects.
