What would you do?
I just the 16-channel main guy.
It's eight channels plus a master. I really should look around for an expander, though.
I know you're on logic, so it may apply differently, but are you able to set up hot keys so that you can easilly switch faders to be audio channels, groups, fx, etc?
I was reading about in the past there was an issue where if you hide a channel in the DAW it still shows up in the faders. Is that an issue for you? THat may be a Cubase specific issue.
I've read mostly good things about the gsr-24 with the worst being that the preamps were vanilla. It being discontinued puts a damper on it as they are not cheap. If your leaning that way ive only heard good things about the yammie dm2000. Or 02r96. Ive had my eye on both.
