I’ve been using GP with an old MOTU Ultralite Hybrid Mk3 for several months now. Everything was working ok, but I wanted to upgrade the audio interface to a Thunderbolt interface. The Quantum seemed like a good choice, but it doesn’t use any front end software (like MOTU’s Cuemix), so I knew I’d have to route a few thigs differently. My current system is a Win 10 Pro, NUC i7 11th gen with 64 gb RAM & 2 TB SSD.
The problem I’m having appears consistently when I open a 2nd instance. The main outs will mute themselves for no apparent reason. Suddenly, all rackspaces will show no audio activity in the main outs. I’ve tried various buffer settings (64, 128 & 256), with the same problem on each. I did a test with a single rackspace on the 1st instance and just a single rackspace on the 2nd, just to test whether the interface is multiclient compatible. Everything worked, so the issue appears to be related to the workload.
Actually- you may be right. I’m scouring Presonus’ forum & finding a lot of people complaining about other Quantum interfaces not being multi-client… although I haven’t found anything about the 2626 yet…
From what I’ve read, it’s not the most stable device on Windows systems.
I’d return it. There are plenty of tried and true options out there that are just as good.
