1. Take your sample.
2. Trim your sample.
3. Set play x: to ZONE in the upper right hand window.
4. hit F3 "zone".
5. Hit open window and set the number of zones...16 zones means 16 pads...4 zones = 4 pads....ect.
6. you can trim your zones to match the waveform peaks by selecting the zone numbers and cycling through them....this is under "play X:" upper right hand corner.
7.Hit edit and turn jog wheel to time stretch.
8. Hit F2...which is BPM match. This is beat matching and tempo matching. You have to play with this. Somebody else will have to explain this one. I'll say this though, I slice my samples and most of the time do not trim them (unless they are drums or horn stabs, chords). I beat match them so that each sample is 1 beat out of four. I can hit each pad in succession and you would not know its chopped even though if you play the pads they are not perfectly sliced on beat. (waveform peaks)
9. After you you hit F5 "do it" and bpm match, it will take you back out to trim screen. Hit F5 "edit again it should be on slice sound. Make sure it says yes to "create new program", and hit F5 "do it" to slice the sample.
10. Now come back to the main screen and you should have your chopped up sample across your pads.
11. Don't forget to save your program.
12. Have fun and play around with this feature.
