As other reviewers have stated, this unit was released with MANY bugs, with new ones introduced as the fixes came in - however, in the latest firmware it does seems to be much more stable, the CV clock inputs are working now, and the random dropped / triggered notes are a thing of the past (with my unit at least!)
I for one am glad I stuck with it - it is a brilliantly fun unit, very easy to start using and with a lot of powerful options to use. I have recently had this unit powering two CV sources (Dark Energy, and my modular) and a drum machine (MFB-522), in perfect synch with no issues. I have also had the BSP clocked by Pamela's Workout, which was in turn having it's tempo changed by the modular, in part controlled by the outputs of the BSP - so a bit of a controlled feedback loop going on, and it worked brilliantly.
The unit itself is solid feeling, the knobs are nice and firm, the USB connector is a bit weak feeling, but I haven't had any issues with it so far.
So - ignore the nay-sayers and get one, it is well worth putting up with the occasional glitch, which are much less common now anyway.
