The 9 sample limit with apTrigga has not affected me at all yet. So far 5-7 samples has been plenty for any project I've had to use samples on. And it's 9 samples per *instance* of the plug. You could always copy a track and edit out certain hits to only be played on track 1 and certain ones on track 2, and use different samples on both tracks, like one for hard/medium hits, one for ghost notes, etc. I've done that before, and as long as you have a pretty elaborate sample set of the *same* snare then it sounds totally fine. Or most of the time I bring the original snare's ghost notes up using compression and fiddle with threshold and sample wet/dry settings until I mostly hear the sample for hard/med hits and the original snare for ghost notes. Works quite well.
Nothing major, task-wise.
