I agree with you Craig. Although the thread title doesn't state it, the OP does specifically say "in SONAR." Without knowing workflow or other details, options outside of SONAR may not be required nor desired, but it is worth mentioning what is available for future reference.

If I may ask, how are you applying trimming ?
Are you using destructive clip editing in preferences ?
Because normally wouldn't you end up with the whole slice, plus the slices slip edited data ?
 
Great tip (using the tab). I like this.  I typically select Autosnap and chop that way.

Great Craig, answered!! ACID wav, within Sonar.
Slices from an ACID drum loop, dragged and dropped to session drummer3, worked brilliantly (the slices take life with velocity sensitive pads); also an ACID loop sustained pitched slice, dragged and dropped into an empty oscillator in Rapture Pro, worked even more brilliantly (with transposition I played a whole melody out of a note).
For auditioning I understood the SHIFT+SPACEBAR, but I prefer opening Loop Construction View and audition there, because the split command does exactly what LCV plays and in LCV you listen before slicing, so you can also edit.
 
Thanks a lot, I was lucky I posted a question that was about to be answered in a weekly tip!!!!
