Hi Bill:
Thanks for pointing out these problems. I can't resolve the first one other than suggest that a foot pedal activation might work if you are willing to take the solution that far. I agree that the cymbols need to be activated correctly in performing NY, NY.
Your second issue can be resolved by downloading a small program called "Padmaker" from the PSR Website. It takes a small learning curve but can do exactly what you want. I'm guessing you would have the final custom Multi-Pad installed in the user area of the 970 or on a memory stick would work well for you.
Good luck on finding the perfect solution. Don Mason probably has a dozen other options for you.
