Participation in the beta program is voluntary. If you don’t want to be a beta tester, don’t take the betas. The betas are NOT on the firmware pages to download from Elektron directly (the same support page from above), you have to get them from the forum here and the very first post says you are agreeing to be a tester.
If your freezes are on a beta, you are a voluntary beta tester based on the agreement on the forum page for participating in the beta. Are you running 1.35B (the latest official firmware from the elektron.se page) or are you on Beta 1.36_beta2 ?
I agree, it would be nice to have something closer to Ableton’s Centercode beta bug reporting system - it is very nice. But the rules of engagement for Elektron’s firmware betas are clearly defined in the beta post’s “reporting issues” thread. It is what it is.
If you aren’t on a beta and have these freezing problems, then I agree, this is a very frustrating thing. If you are, well, you get what you paid for. You’re a voluntary beta tester.
