My CQ is fantastic and checks so many boxes for my band’s use case. I use the audio interface functionality of the unit to trigger edrums through a VST in Ableton, in addition to the CQ doing its traditional duty of running all of the other band inputs, main mixes, and monitor mixes.
I’ve noticed a pretty big difference in audio interface output latency with Windows vs MacOS. On Windows, at 128 sample size / 96k / CQ ASIO driver, I get a fantastic 1.5ms output latency (see pic). On MacOS, at a 128 sample size / 96k / CoreAudio, I get a lukewarm 4.34ms output latency (see pic). As my Mac is my live rig computer, this isn’t super ideal because there is additional latency elsewhere in the signal chain (scan time latency, midi latency), all additive, so it can make my edrums in my monitor start to feel a little mushy.
I know that audio interface development probably isn’t Allen & Heath’s core business, but is there a chance we could have some resources assigned to the potential development of a MacOS / CQ driver? CoreAudio is OK, but other folks like RME, Motu have MacOS-specific drivers which I would imagine help improve latency performance on their interfaces.
