I am very satisfied with the overall performance of the CQ20B console, both for the speed of implementation, the ergonomics of the application and, most importantly for me, the sound quality (live and recording).
During the concert, I was able to record a 10-track live performance in 24 bit/96 kHz without the slightest problem and then mix the recording on Cubase.
The only thing I had to deplore was the bug in the CQ MixPad application on the iPad which was unable to process the touch event of the input tab (1 to 8) for a few minutes. Even when changing screens (config, processing), the bug lasted for a few minutes. I have a video available if necessary.
I think that the management of threads or events contains an error in certain situations following events or actions produced before.
