This is tricky, there is a race condition in the cue manager that I don't quite understand fully.

A workaround that does work is adding a 'window' in which two differing cues are considered the same. Two cues that are 60ms apart will be treated as the same. How precise are DJs about their cue point timings? This window might annoy someone because they won't be able to adjust finer than within 60ms of a given position.

A 60ms window works fine at 20ms latency, but at 40ms latency it doesn't.

Very precise with cues. First beat of first bar just like vinyl or cdj

This is tricky, there is a race condition in the cue manager that I
don't quite understand fully.

A workaround that does work is adding a 'window' in which two differing
cues are considered the same. Two cues that are 60ms apart will be
treated as the same. How precise are DJs about their cue point timings?
This window might annoy someone because they won't be able to adjust

Barring some serious epiphany, I don't think this is fixable until the engine is in better shape.
