Lee, re: > 1. You can have polyphony of 16 for any of > your mapped samples. Polyphony does not solve the problem I mentioned. If you set polyphony to 2 for the hihat group, a closed hihat won't shut off an open one. So you have to set polyphony to 1 in order to solve that, but in the process you end up with open hats shutting off open hats, which sounds completely unnatural. Natural-sounding hi-hat grouping is not solved by polyphony, as I mentioned in my previous email. re: > 2.

I'm pretty experience with Environments in Logic, and I know that this does not solve the problem. By needing to highlight the EXS instrument in the Arrange window, you cannot use an EXS instrument as part of a drum map. This is one of the (now-known) limitations of Logic with the EXS. Seriously, I do appreciate your help. But I'm pretty sure the problems I mentioned are unsolvable, and are a blatant limitation of the programm, as it currently stands. Noble
