Nice synth. The ADSRs are a bit slow for my taste though, not enough punch. But I do like the sound of the filters. You should get a controller unit. These Rolands can be controlled pretty well with CC or Sysex.
I still have a Nordlead and a MicrowaveII, but it's been ages I hooked those up.
regarding the controller unit, the behringer bcr2000 works well, and theres also a software based interface for mac i'm going to try. in general i don't mind too much the digital editing method, but its nicer to see it all visually.
my korg is an ms2000r by the way, and i also have a x0xb0x. i had once a novation bass station, but i sold it.
i never knew you were into synths hunter!
