I have similar behaviour with the clock - sometimes being one sixteenth off. I normally send triggers by ear and not care too much about the classic positions of where things should be ie kicks on 1, 5, 9, 13 in a 4/4.

Sometimes it works fine though, so I'm presuming turning of and turning on the modular has some form of effect.

In my case all the triggers work though so if its a DIY, it could be a soldering issue
