well there is a way. Look at the manual to see how to boot it in sound module mode. (You need to press a button when turning it on, don't know wich one anymore) You cannot use any knobs on it anymore, it's just a module in this mode. But you can controle several parameters through midi. Well, not all, and not the freq cutoff and resonance
unless you start sending NRPN's and start digging deep into midi programming.
