30+ years ago I managed to connect my Roland GR-1 guitar synth to my computer.
I don't remember the software I was using at the time, but I was able to record
the synth sounds in the GR-1 to computer.

I would like to do the same today, use my GR-1, but this time with RealBand.

If someone can give me guidance on how to make the basic connections I'd really appreciate it. smile
My GR-1 has Midi IN/OUT. I plug in my midi-enabled guitar into the GR-1.

So the GR-1 is both a midi controller and midi synth.
I would like to get at the synth sounds in the GR-1 and record them in RealBand.

I also have an Edirol UA-25EX audio interface with midi IN/OUT and a USB connection.
