Hi,
Not sure if I got exactly what you want to do... but the attached PD [1]
patch is a simple bandpass MIDI-controlled patch... It uses note pitch
for centre frequency, velocity for Q and control 7 for overall volume
(all on channel 1)
It isn't multi-band but could easily be extended to be polyphonic.
You should connect, via jack, the audio source and MIDI keyboard to PD.
Lorenzo.

I found one way with ingen. I load note module, which converts note to frequency, trigger and etc, and connect frequency to plugin frequency parameter, which has different name (afaik, portamento... in short, it is first in parameters list). Though i need also to map frequency, generated by note, to portamento range.
