I own an old D-50 and this thing outputs all the usual Midi stuff and was, I believe, one of the first Roland synths to have full Midi capability. It also pre-dates the XP50 by at least a decade.
I'd be surprised if the XP doesn't do this, but I bow to your greater knowledge if this is indeed the case.
Hey, you write great stuff here, I don't think you need to bow for anything!
I guess I'm a little confused here as to why you are talking MIDI when the OP appears to want audio - the OP appears to want to be able to play the XP-50, whether manually or thru MIDI output from Sonar, and to record the subsequent audio coming from the XP-50 into in Sonar. You can't mixdown a song that uses the XP-50 as long as the actual audio is still coming from the XP-50. MIDI will not transfer sound, it will only transfer MIDI data which contains no actual sounds. Where are the oscillators used to create the sounds? Where are the wavetables/partials? How is it that you propose that the sound output from the XP-50 can be translated to MIDI data and be then sent into Sonar and subsequently re-converted into audio?
When you say it outputs "all the usual MIDI stuff" you fail to address the issue which is: how do you transfer the -audio- from the XP-50 to Sonar?
