e lter cuto is normally controlled by the "cuto/rate"
knob. But with the VCF activated, the lter is insted
controlled by an envelope that will sweep the lter cuto

lter cuto knob for you, when hitting a note. :)
is envelope is triggered by the guitar input (by default).
For this to work, the threshold needs to be adjusted to suit the
guitar signal-strenght. - See page 15 on the threshold control.
