I’ve had one crash in dozens of hours of use. Not bad for a non-final OS, from my point of view. Yes, I admit I have a biased point of view having a smooth experience and still in my Elektron honeymoon period. (Plus I come from Korg electribe world, where you get 26 megs and sequences get stale fast.)
The Digitakt is vastly more stable than my iMac. Or my car. Or my brain. All of which I paid far more for.
