LFO: Sets the amount of the modulation from the polyphonic LFO to the Filter's Cutoff
frequency. The LFO is added to the Filter's Cutoff frequency in a bipolar way, so that the
Cutoff control sets the center value that the LFO will modulate around.
BASS: Sets the amount of Boost or Cut for Bass Frequencies. When rotating the knob to the
left, it will boost Bass frequencies, but rotating the knob to the right, it will cut Bass
frequencies. No boost or cut is applied when the knob is in the center position.
To describe this more accurately, from 0 to 50% travel, the Bass boost Filter begins to
function. After 50% travel, this is nulled and a High Pass Filter is enabled.
FM: Sets the frequency modulation (FM) source and FM amount for the Filter's Cutoff
frequency. When rotating the knob to the right of the center, it increases the amount of VCO
2 FM to the Cutoff frequency, while rotating the knob to the left of the center, it increases
the amount of Noise FM to the Cutoff frequency. There is zero modulation applied when the
knob is in the center position.
TRACK: Activates Filter key tracking, which is the modulation applied from the note played
on the keyboard to the Filter's Cutoff frequency. By pressing the TRACK button, it cycles
through 3 tracking amounts: Zero (LED OFF), Half (LED flashing), Full (LED ON).
Whilst Full tracking is selected, by setting the Resonance at maximum and the Filter Cutoff
at zero, it will allow the Filter to be played as an Oscillator and it will track notes as a normal
Oscillator. If the notes are not scaled properly, proceed with an autotune. For more info
please check the MENU section.
With Filter key tracking, the higher the notes are played, the brighter the sound will
appear, which is a typical characteristic of acoustic instruments.
