I found that using Pianostyle chord recognition does the best job of avoiding the 'glitches', as the arranger won't even TRY to play a chord until three notes have actually been played (it's usually guessing until the third one goes down in most other systems!). And 'Intelligent' or One Finger systems are the worst, as the arranger might see the root first, decide it's a major chord, then when it sees the minor 3rd, it will then glitch to that. Or whatever you end up playing...

Yes, leading by a hair is optimal, but hard to pull off and lay back the RH. Might be why most arranger user demos always sound a hair 'rushed'. Tough to anticipate with the left hand, but drag and sit back with the right!

TBH, whenever I prepare arranger output for sequencing and subsequent additional work, I always play the tune in full piano mode, as a full but simple piano part. That way, any inversions get played, and I can concentrate fully on simply having both hands push a tiny fraction, sit 'up' on the beat, and avoid most of the glitches...

Then I can add other parts and sounds, and do the solos, in the pocket that best works, independent of what my LH chording had to do.

I think most arrangers now try to do a 1/16th recognition of chord input syncopation... perhaps this might change to a 1/8th at very high tempos (be nice if they did, anyway!), so at a brisk tempo, you had better be on it anyway!
