@dezwo I had my Deluge crash three times. Once with the stock firmware, twice with the community. I don't think that means anything.
If I was performing live, I'd be hesitant. But I'm not, and the community firmware comes with _so_ many improvements big and small that I'd be missing out if I didn't use it. I don't regret upgrading.
That being said, I'd love an "auto-save" feature, but saving manually every few minutes doesn't really hurt either.
Let me know if you have any more questions.
@dezwo Also, the community firmware definitely is the future. It has made lots of refactorings, which means that merging single features back to the Synthstrom firmware is hard or even impossible.
I expect (and the community devs do, too, afaict) that the Synthstrom firmware won't see much development in the future. Instead, the community one is where features & bugfixes are going to be.
It's already so much better than stock, and the stock firmware was already pretty good.
