Qu usb recording high disk usage with Logic Pro

[Dean]

Hi folks
So I was doing a 8 channels multi-tracks live recording with Qu-16 with Logic Pro
and there the HD bar keep peaking and stop recording from time to time with that disk too slow message
I am already using an external SSD hard drive. And my colleague had the same problem with his Qu-24 too, which he has no problem recording with a Dante but can’t do it with usb. And he had no problem after switching to Wave Tracks Live. Is it a sample rate problem? Or problems with Logic Pro and Qu mixers? Any thoughts?

My mac spec:
Mid 2015 MBP / IOS 10.13.6 / 16gb DDR3 memory
The project is 24bit 44.1

@Dean,

The Qu runs at 48kHz, so a project at 44.1kHz requires sample rate conversion to be carried out by the computer.
This can cause the ‘disk too slow’ message with Logic, which is quite a resource-hungry program as-is (unlike Tracks Live).
Please try running a project at 48kHz to see if this helps.

Thanks,
Keith.
