Hi Groovyband,
thank you for all the info, it is going to take me some time to work thru what you said. I did download your demo, but, at the moment, I have Xmas guests coming to stay ( I hope) so don’t have the luxury of time to work my way thru it. After Xmas I will definitely check it out.

I tend to agree with Henni, the fact that you use a psr with your software is sort of misleading, it at first gives one the impression it’s a psr style player like One Man Band, and the old Live Styler program from many years back, even Dan’s VArranger 2.
It sounds like you possibly could have picked a different brand of keyboard like a Korg or a Roland to base your software around? but Yamaha might have been the easiest to work with, I don’t know anything about programming , so just guessing.
I think as Henni said, one needs to treat it as a seperate instrument an arranger in its own right, that just happens to use a psr as a base .
