Hi, is there anybody knows on what basis the knobs work? On Akai APC40 there are very similar knobs but far better. Unfortunately I sold mine. When I will have more time, I will make measurements if it is pot or encoder. Yes they looks similar, but it is different. It would be awesome to have zaquencer with better knobs or even encoders. I will be my next project after synth on what i am working now. I thing this machine is worth it.
