I've got an offer to exchange my old 5str Sammick for an RT-323 drummachine. Now I use soundfonts for drumprogramming since I've got no other way to get drumsounds. Does the RT-323 support layered drumsounds (different sounds for different velocity)? I never play the sammick anymore, but I've had some thoughts about defretting it. Is the RT-323 any good and usefull or should I keep the fivestring and try to defret it?
