I've got the Pro-8 which is the same synth i think...
I use it as a pad machine, envelopes aren't too fast on it. it's one osc per voice but you can mix 3 different waveforms which is kinda cool. the filter steps which a bit of a shame but sounds nice enough. fairly thin sounding synth but quite warm with that, unless it's in unison mode, then you get a fairly heavy sound from it. programming it is really sweet, matrix of buttons and one data knob. biggest let down for me is the midi/sysex implementation. i suspect it can handle sysex control, but no one on the internet has any info on the sysex codes
it's a nice, unique sounding (at least in my setup) little synth and i wouldn't sell it.
here are the SysEx strings for the Max
might help out!
