Analogue-sequencer

I'm running into midi clock issues, slaving the p3. It appears to be related
to Cubase, since I don't experience the same problems with Numerology and
Bidule. I also don't think that it's p3 related, since I have the same issue
with my Spectralis.

If I have the p3 synced to Cubase, and the Cubase looping, what happens is
that often, but not every time, when the loop is restarted, the sync goes
crazy for some short though very disruptive amount of time, by speeding up.

I can't find any settings in Cubase to fix it, and I'm about ready to ditch
Cubase unless I can find a solution.

There is definitely no midi loop.

Anyway, I'm hoping that maybe someone else has encountered this, and has a
fix.
