Anyone have RTL numbers for CQ mixers (specifically used with a M1 or M2 Mac, but other systems would still be helpful)
Thinking about purchasing if I can sell my old interface and use a CQ-20B for double mixer/audio interface duty, but wondering what minimum latency I could get running 96khz on 64 or 32 buffer on my MacBook Air M2.
The actual round trip latency is so dependent on the exact setup that we cannot provide a single or official figure.
But to give you some idea I’ve just carried out a quick test.
CQ-18T, Multitrack, 96kHz, M2 Mac, 64sample buffer, testing using RTL Utility routing USB to input 1 and returning from the Main LR (so note this figure also includes all internal processing).
= 7.2ms (total roundtrip)
I also confirmed before and afterwards that I could route signal from the computer, back out to a reverb in Live Professor and back in to a stereo channel without artifacts (mainly to show to myself that it was stable with at least one fairly chunky plugin running and not a useless figure!)
Thanks,
Keith.
Thanks Keith - do you have any similar numbers for tests on the QU series mixers as well?
Any chance of getting those latency numbers down? Say via a kext on Macos?
Is it technically possible in the future to route an input to USB OUT, process it in a VST host and send it back again to the same input ?
Like the X32 does for example ?

I’m thinking about buying the CQ18T, so I have the following question about latency:
With a 2001 Imac, the console produces 6.6 ms RTL as audio interface at 32 buffer size and 48 khz
With a new Macbook Air with M3 under the same conditions 9.7 ms RTL.
Even if I do the monitoring in the console, the problem remains when recording via USB if I assume correctly -?
