Thanks for the reply! I think that going with the Atari at this point would be more of an aesthetic choice than anything else, but also because I have heard that they allow you to use hardware synths with very low latency....though most of my hardware synthing will be done from a purely compositional standpoint, so I guess it doesn't really matter.
This info on midi events is extremely useful. I am sure I can do something similar within logic pro x. I guess the real question is how to figure out which values I need to input for the SC-88. I believe that I can actually save patches too, but it's a bit convoluted to understand without the unit sitting in front of me. I just ordered one recently, so I haven't had a chance to play around with it yet. Any idea where I could find the associated values i need? I guess they would show up in Logic right?
