almost every request in this thread so far is a good one. i'm pretty sure JJ is checking this forum out so hopefully he is getting some ideas.
tops requests for me would be:
1. midi control of PROGRAM screen parameters (the holy grail)!
2. a new column in the PROGRAM screen where you can choose L, R, or ST (play left, right, or stereo channels of a sample. potentially big polyphony savings. better than destructively converting the sample to MONO.)
3. in the TRIM screen: the ability to chop a sample as it plays back by hitting a pad. this will create a slice at the playback bars current position whenever the pad is hit (very useful).
4. REVERSE option in SEQ EDIT.
5. even better: realtime REVERSE sequence playback, choosable on the fly. imagine seeing the playback bar going backwards in the MAIN screen/GRID EDIT!!
6. ability to have TRACKS with different lengths looping in the same sequence (example: TRACK 1 is 4 bars, TRACK 2 is 7 bars, etc...)
