• KEY TRK (VCF Keyboard Tracking)
Range: -32 ... +63
This determines the degree to which the VCF "tracks" or follows the keyboard. In other
words, the higher the notes played on the keyboard, the more the cutoff frequency is
raised (or lowered). When Keyboard Tracking is applied, the cutoff range shifts accord-
ingly at every note, with C3 as the base. Positive values will cause higher notes to have
a higher cutoff point. Negative values cause higher notes to have a lower cutoff fre-
quency. A value setting of "0" results in no key tracking.
• When this is set to "+32," the change in the cutoff frequency matches (or is directly propor-
tional) with the change in the keyboard notes.
FEG (Filter EG) Parameters
The FEG parameters determine how the timbre of the pattern changes over time. This
lets you produce subtle or pronounced filter effects (such as wah, for example).
The EG DEPTH parameter (in the VCF block) must be set to a proper level for the FEG
parameters to have an effect on the sound.
• The FEG can also be used as a control (in
, etc.), giving you even greater sound-shaping flexibility.
• DEPTH (Filter EG Depth)
Range: -128 ... +127
This determines the range of movement of the cutoff frequency. This must be set to a
proper level for the FEG parameters (Attack, Decay, Sustain, and Release) to have an
effect on the sound. Positive values increase the Filter EG Depth. Negative values
reverse the shape of the envelope.
