I use the Model 24 with CbB and like other users, it took me forever to figure out the DAW playback channel was 21-22. I don’t feel like there was enough instruction in the manual about using the mixer as an audio interface. One issue I’m having right now is the fact that when you record, the compression and EQ strips are bypassed, recording a totally dry signal. The problem is sometimes you want to notch out some low end or add a tiny bit of compression to a vocal. I opted for using a tube mic preamp instead but I still feel like this should be a capability of the mixer. It would be nice to have these kinds of things switchable in a mixer to make it more flexible. As far as recording and performance, it seems to do a good job. I also had a problem with showing only the odd-numbered inputs so I’m hoping to fix that with the above recommendation.
