I always use this method (time slices) since Pa1x up today in my Pa3x...
In my new Greek Locked Project of Korg (Ultimate Musicorama), all percussion its with Time Slice method...
All percussion loops recorded in top Sierra Studios in Athens (SSL G Series Console, and top Microphones).
The name of percussionist is Kostas Meretakis (top player in Greece).
Korg Triton,s and Kronos also used this method..
