Love to play with and watch this thing run. Build quality is super, everything works fine and I think it makes me sound much more musical than I actually am.
The UI as seen on the face plate is very intuitive - however going past the basic 8 steps means menu diving. There are more than a few buttons and procedures to memorize. I'm slow, this took me time to get into my head (and hands).
It's a total drag that the extension module (Ostankino II) has to be purchased just to get silly CV speed control and a clock out - Meh.
Zero regrets to buying both the rotosequencer and the extension module, but then again I have lots of rack space.
