I've been running a hybrid setup for a while. My console handles 96 inputs for mixdown, but I only run 32 channels or less. I want to limit to 16 channels for a more recallable setup that stays in the sweet spot of the mix position (using channels 17-32 in the center). 90% of what I do is rock projects. I need control and rideability, but also streamlined workflow. Really struggling getting it below 22 channels. Need suggestions! I suppose it would be similar to those running 16 channel summing.
