hm.. i've had a mr76 for awhile now, as far as synthesis goes, i'm not sure exactly what you can do with it other than run it though the onboard effects and control things like ADSR.. however, you can probably do all kinds of stuff that i don't know about mainly because over 50% of the time that i've owned that machine it has been broken or in the shop. too bad, i love the pads, strings and some of the real voices.
