Usually good. But not in jazz.
1. Play the song perfectly. Note to self: THAT ain't happening.
2. Quantize each & every Count 1 note one at a time, and then go into MIDI editor and slide all the other notes that aren't perfectly timed.
Note to self: Don't WANT that happening!
When you quantize, you'll still have the swing - but the timing will be perfect
