I use my QU24 as a soundcard with either Ableton and my ipad. I manage to use channels 1-16 successfully, but I can only get the first 16 channels into my DAW. The channels 17-24 show signal on the mixer, but don’t feed into my DAW, although they are recognized as input channel, they stay silent. I checked all the routing options in the 17+ channels, they seem to be aligned with the 1-16 channels. Both my Macbook and my ipad are top spec. Might there be a setting which I have missed?
