I don't use the matrix myself, but I do have many hardware synths.
If I have a chance over the next few days, I'll give it a try. John says he got it to work, so I know it's possible.
Bapu's comment seems pointless..
@chuckebaby - yet again you storm into a thread, misunderstand the OP, and feel the need to "jump on the guy". This is not a hardware issue. I'm guessing that you, like many, think MIDI applies only to softsynths.
As someone who grew up before MIDI, and owned one of the first MIDI synths, perhaps I see it differently. MIDI is a universal standard. Comparing the OP's issue to your wanting "Mark Bass" included in Sonar is ridiculous, to say the least.
Your comment "I think we have dissected and analyzed (sic) things a little to much when it comes to what should and should not be basic features" begs the question that perhaps you need to analyse a bit more before jumping on your soapbox?
Peace, man. We all make mistakes, but chill a little before jumping in with both guns blazing.
@OP - If I get a chance tomorrow, I'll hook up my 'boards and play around with the matrix..
