Thanks for all the input. A number of different approaches to basically get the same thing accomplished. Jamorigin has a demo, so I think I will download that and see what it can do. The midi obtained from my GR-33 also took some editing to clean up. Depending on what style I was playing, it would add some notes that I am sure I didn't play! Just kidding there. This whole recording thing has revealed quite a bit of sloppiness that I just didn't catch going live. And I agree, the guitar output side was bit noisy. I definitely need something that does multiple notes and chords. Melodyne is a definite option, and I have done a few things with it that have turned out well, except I noticed a few notes Melodyne processed that are slightly out of time with the audio recorded.
I will come back to this next week after returning from eclipse watching. Thanks again for everyone's input!
