[QuikDraw]

I just picked up a Quantum 2, and I have to say I am impressed. I haven't tried it in Mac yet, but my Windows 10 Bootcamp installation works great. I get better stability at 64 sample buffer than I did at 256 samples with any of my other interfaces. Latency is not noticeable by me, and I have no problem tracking though Amplitube 4 or any other plugin I might need.

Interestingly, I can get the buffer all the way down to 16 samples in the Studio One 3 Artist software that came with the interface. And it seems to be stable at that setting as well. Pro Tools doesn't even see 16 samples as an option, and 32 samples is too taxing on my aging system. But none of that matters since I get acceptable (unnoticeable) latency performance at 64 samples at 44.1 KHz. And I like Pro Tools too much to bother learning another DAW right now.

Update: I tried it on Mac High Sierra, and it's rock solid stable at 32 sample buffer. I played with it for only about half an hour, but it ran perfectly with a few different sessions.
