Well, I just looked at sound forge and unless I missed something I didn't see anything there about sample accurate syncing. In my system, most of that is done on the sound card settings. You'll know you got it right if there is no poping, clicking or other noisy artifacts from the digital transer. What happens, is that the two clock sources... the one in the roland and the one in the computer slowly drift apart and cause a pop. That can happen pretty quickly, within a few seconds, or over a period of minutes. So if the transfer is flawless, good job, if not, let us know.
The midi syncing should be easier. You basically find out which systems either MTC or Midi Clock which your software and roland use. Pick one, (I am not sure why, but MTC appears to be a better choice... or so I am told). Pick one as your slave and the other as master. Make sure that the master is sending on a midi port and channel that the slave is receiving. Check to see the midi devices match on the two systems. Set the smpte rate... most people who are not scoring a movie use 30 frame non-drop. Set the slave to do whatever (either record or play... it shouldn't start to do anything... it is waiting for the time code to start, on my instruments, I get a message like "waiting for 30 fram non-drop time code"). Start the master and after about 1-2 seconds the slave should start. It will "jump ahead" so that is matches the master's position marker.
The breaker will be if the systems don't both use either MTC or Midi clock.... I think there are some work arounds, but I don't know what they are.
Hope this helps. Good luck!!
