Filter frequency keyboard tracking.
2005-12-13 by Ronald Pieket
Has anyone figured out how to get 100% keyboard tracking on the filter frequency? If I set a patchcord from "key+-" to "filtfreq" to "+100", well that seems to do something, but it is way short of 100% keyboard tracking. When I set up a second patch cord with the same routing, and a value of "+30", it is pretty close (not perfect) on some filters, but changing the filter type changes the tracking behavior again. I test this be selecting a sawtooth waveform, cranking up the resonance, setting the frequency so that I can clearly hear one harmonic, then playing all the keys, hoping to hear the same harmonic across the keyboard. What am I missing? -Ron.
