Hi Larry.
About the R1 and R2 thing... That's because of the KN3000 built in sounds vs the KN7000 built in sounds converting process. This would happen anyway. A fork in the road that can have it's own discussion...
I'm getting my PR900 songs converted first in PR902 format then in PR804. I have to adjust the R1 and R2 One octave lower, and the Left one Octave Higher to get the original octaves back.
You know this is the tip of the iceburg, once you have the pre-built rhythm patterns in the composer, you are now able to tweak these some that was not possible doing it the other way. Say Accomp 2 had a flute, and you wish it was a sax, you can change it, and have that sax.
One thing you need to be aware of, if you use a memory sound, make sure you save it, that's the *.tm file.
Have you checked out the MSA using the composer? I have more info on this and will post later if your interested...
