|Filter sweep by MIDI Aftertouch
(by request of Martin Hatfield)
This is not really a trick, but it is useful
nonetheless. If you allow aftertouch to control filter cutoff (edit parameter 55
non-zero), then you can use your sequencer to control the cutoff by "drawing" an
aftertouch curve instead of recording it from the keyboard. This way, you can have
complete control over cutoff frequency, and also use the LFO for other things. Check out
the Sound Gallery for an example of this.
