Key Track
KEY TRACK allows the cutoff frequency of the LPG to be set by the note
you’re playing. If KEYTRACK is 0% the cutoff frequency of the LPG is not
effected by the note value and is set by the FREQUENCY knob only. If
it’s 100% it is modified by the FREQUENCY knob, but also scales with fre-
quency so all notes will have the same timbre.
Frequency
The FREQUENCY knob loosely controls the maximum cutoff of the filter.
It’s not exact because the underlying modeled circuit doesn’t really
map to frequency well.
Resonance
The RESONANCE knob controls resonance of the LPG filter when the
POLES control is turned greater than 1. This control is not active at all
when POLES is at 1 and becomes more apparent the higher POLES is
turned.
Poles
The POLES knob morphs between a VCA style Low Pass Gate (one pole
low pass filter) and a resonant (three pole) Low Pass Filter. Modulate
it.
Attack
The ATTACK slider controls the attack time of the ADSR which drives the
LPG.
