I not sure that it will work out that way , I think you may be quite surprised in a good way. I’ve had that GR33 sitting on the floor for the last 3 years untouched and once it was wired up again…it was pretty cool. I think you have a nice surprise coming
I did a track of Dave Brubecks “take five”, the repetitive piano part I can play …so it got midi’ed into Cubase …then took the GR and played the sax part on the guitar. It came out very nice for something stuck together in about 7 minutes. I experimented just using the audio track from the amp, mic’ed. I will try adding the midi out from the GR33 and use that input to play thru the MT32 or the GR( maybe )
But I’m just giving you a heads up…you’re gonna have fun with it.
