Apple silicon

I would guess Serum is going to be ported at some point, but just wondering what the likelihood of OTT making the crossover ?

very likely!

I have added Big Sur support (beta) and it should run via Rosetta2 on Silicon machines:

Brilliant stuff, if OTT lands native on AS, it is one of the things that would push me in to it, strangely more so than Serum hahaha, I know I know, I bought Serum to pay for my OTT usages hahaha.
