I've had the Keystep for a couple of weeks now, and one of the main features that sold me on it was the built in arpeggiator. I have noticed that when using it with the tap tempo the tempo drifts out of time Alot! it almost seems as though if you don't hit the keys at the EXAct Exact moment the whole arppegiation in thrown off. ive tried everything for buy a more expensive midi cable, ive used it as a controller for my moog slim phatty and for software synths. any corrections in future up dates?
