Delay Time Oddness

Hey there

I have my A4 Midi Transport Sync’d and Clock Sync’d to my Octatrack. If I have a trig on the first step of the A4 with the track being sent to the Delay, when I press play on the OT the Delay sounds like it’s not in sync and takes a split second to come up to speed making a tape warble effect (like when you adjust the time parameter).

Shouldn’t these two puppies play like gold together?

Only fix I can see is to set the tempo manually on the A4 and have it only sync to the Transport (which also weirdly I have to set in the A4 and not on the OT where turning OFF Clock Send doesn’t appear to do anything).

Dang, my brain hurts learning all this. What am I doing wrong…

the delay time is synced to the A4’s tempo. It sounds like the OT is only transmitting it’s clock while it’s transport is running and the A4 reverts to using the internal clock when it’s not receiving a clock signal. perhaps there’s a way to set the OT to always transmit clock regardless of it’s transport state? otherwise you could just slave the OT to the A4’s clock instead.

Here’s what’s likely happening:
when you first turn on all your gear, the A4 doesn’t get clock data, so maybe it’s set at 120 bpm internally and waiting for new bpm info. When you hit play on your OT, it sends the new clock and the A4 corrects.

I bet it you waited 1 cycle of your pattern and then brought in the A4 it would be OK.

This happens throughout. Only fix was to not send midi clock info and manually set the two tempos. Not an ideal solution to be honest. Urgh.

so it’s a drifting bpm? I thought that was fixed in the last update…?

Yeah, that was happening also in the last OS (bpm drift when changing pages) but I updated and that fixed that. This seems to be when the transport starts. Weirdly, I tried to recreate last night and it wasn’t doing it… oddness. Gotta love Midi.
