Any subtractive synth should be able to do this. AMS (ALSA 
Modular Synth) is the first that comes to mind. 
Others to look in to are Ingen (similar to AMS) and 
ZynAddSubFX/Yoshimi.

Another option is to take midisine.c from the JACK example 
clients, and modify it to respond to MIDI velocity or some 
control parameter (CC).
