Issues with MIDI seem to be coming thick and fast for me at the moment…
I’m looping a MIDI part that starts on beat 1 with a longish note but when playback loops back round it plays back very short.
The problem is the previous part: its last note (the same as the first of the loop) ends at the end of the bar but is sounding briefly at the restart of the loop and masking the note that should play. If I shorten this last note even by 1 tick the loop plays correctly. If I then restore the note length the loop continues to play correctly. The same thing happens if I leave the note length running up to the bar end and instead shorten the part by 1 tick. Which I find a bit odd; I was expecting the note to play its full length and cause the loop to mis-play.
If I shift the pitch of the last note before the loop up by a semitone, instead of shortening it, the first note of the loop plays correctly but the short now discordant last note of the previous part is clearly audible.
In Preferences > MIDI, Extend Playback Range of Notes that Start before the Part is 0 (as advised by @Martin.Jirsak to a post with a similar-sounding problem I had in 10.5 and Length Adjustment makes no difference (I’ve had it down to -20).
I’ve tried the project in previous Cubases and the further back I go the weirder it gets: octave and volume shifts which must be due to project incompatibilities as I’m sure they never acted up quite like that at the time I was using them. I’ve failed to find the same problem in another project I’ve been working on in parallel but it doesn’t use much MIDI (or the Halion Symphony Orchestra for that matter, which itself is not entirely out of the frame). Anyway, my brain now hurts quite badly so I’m posting this and going to bed. I’m at a loss and it’s holding me up as I can’t currently trust what I’m hearing.
