hi, 

you can create a first filtering rule to drop all events and then a
second rule to pass note events. Voice rules have precedence over
channel filtering rules so notes will pass. For instance:

filtnew myfilt
filtchandrop myfilt {0 0}
filtkeymap myfilt {0 0} {0 0} 0 127 0

This will create a new filter 'myfilt', make it drop everything on
channel {0 0} (ie midi device 0, midi channel 0) and then make it
pass note events on channel {0 0}. Velocity is part of the midi
note-on event and cannot be removed.
