Delay repeats detune when QC receives MIDI clock and sync toggle is ON

One more unfortunate update :

[quote=“ozanerk, post:20, topic:13737, full:true”]

Unfortunately I have another observation. Having all delay compensations set up in Ableton, when I play the project QC’s tremolo/slice effect starts very tight on beat and seems to go flawless. However after some time (a few minutes within the song), when I try again to use my sliced preset, sync seem to be lost. So there is a shift on the clock sync from Ableton. I am not sure about whose fault this is. Either Ableton’s clock out is not consistent and deviates in time. Or QC receives it unstable. Eventually the sync drops.

Update:

I found the solution:

QC not following MIDI clock

I found the solution for this Ableton issue. Ableton company is aware of this drift in time issue with hardware sync, and they put a hardware resync button. Hidden normally, but might be enabled in MIDI tempo settings. It is designed exactly to solve this drifting issue. From time to time during song playback, one can press on it to resync the external gear. I tried it with Quad Cortex tremolo / slice effect. It works fortunately.
