I'm going to respond to the impatient folk on here. I'm not associated with Presonus except as a user.
The Apple M1 is a game changer, and for various reasons I'm now using an M1 before I planned to. I knew that my Quantum wasn't going to work with it, cos I read it here on the site and elsewhere, but I still went ahead anyway and bought the M1.
BUT I'm an amateur, and I don't need the Quantum's full functionality at the moment, and I'm using another Presonus USB 2 channel thing which is working fine.
Also, I have a Macbook which, if I did need to use the Quantum, I could use.
In other words, even I have alternatives, and I'm not relying on the Quantum for a living.
I bet there are pros reading this saying they're not going anywhere near an Apple M1 until this is sorted. And they're right. And then I bet they'll test it out before deciding to shift. And keep the old system as a backup.
So, if you are complaining, AND using the quantum for a living, can I suggest you use your backup system? If you don't have a backup system, why on earth did you move to an Apple M1?
I'm pretty sure, by the way, that Presonus are working on the update as fast as they can, and I'm as impatient as anyone else, but I can wait, as I'm not relying on it for my living.
So, sit back, relax, make some music. Presonus will release it when it's good and ready, and not a moment before.
