Manual Program Change Shifts Downbeat In Some Cases (especially high bpm or over time)

I built out a nice bank of midicake patterns that I can jump between, so the way I cue this live is to press LOAD on midicake and leave that page open so when I notice other transition cues musically I can easily glance over and one press launch next pattern synced with ie: drum machine change

I've noticed a lot of strangeness with this where sometimes the downbeat gets slightly shifted back or forward where midicake's downbeat is off +/-3/16 The weird part is that if I give a long cue to midicake ie: press the next pattern on beat 2 so that it has a few beats to count it starts to lose things.

However, if I time it and cue right on the and of 4 it seems to land together way more consistently. I've also gotten better at a live reset stopping on 3 and restarting on downbeat, but tapping early is far preferable

Some Notes: if I run at 133 or so I need to do lots of manual resets and midicake seems to really only land if I nail the cue on the and of 4

lower bpms had less of an issue ~111 or so, however. If I had previously been at high tempos and getting lots of drift then it doesn't matter what tempo I use and drift expands.

If I do a full power disconnect and plug back in, things sync up better for a bit.

This makes me think maybe there's a memory leak or some traffic getting clogged? I was also sending new chords to midicake to coincide with the program changes and it feels like midicake ever so briefly pauses to process this and then comes in late
