I didn't really talk about my setup, because I was convinced that nobody really cares
Anyhow, here's a long explanation, so maybe you might want to wait until you're on the toilet to read it
So, I use an old Ecler EVO5 mixer, which I have running in MIDI mode. This means that the mixing is all being done by Cross, with the mixer running solely as a controller.
Why have I done this, you ask? Well, because I need to take the output of Cross and send it through a virtual ASIO driver (ReaRoute) into REAPER. This allows me to set up a one-button mic macro, on the mixer, to mute the speakers when I talk on my condenser mic (I'm a radio DJ). The only way to do this was to somehow get the MASTER feed into REAPER and be able to toggle muting it internally without it necessarily being fed to the EVO5 master out. This is actually really important, it's a program I've spend 80 hours on, and it does a lot more than just this. I have versions of it that I've modified to run in my studio here in New York, also a version to run in my secondary studio, and one when I travel.
It works great, except for one small thing... The mixer channels have meters on each channel, which are not controllable through MIDI at all. You have to run a signal to that specific channel, then the individual meter will illuminate. In MIDI mode, however, the signal you route to individual channels will NOT come out of the mixer's audio outputs, not the MASTER, and not the PFL jacks.
So, what I'd like to do here is to be able to get both decks' individual outputs, and send them back to the EVO input channels, so that the meters show properly. It's a waste of bus bandwidth JUST for eye candy, I know, but that's the only thing that functions differently from using it in traditional mixer mode.
PS this is the reason I was asking for Rewire support as well, it would be a lot tidier than dealing with a virtual ASIO driver. Plus virtual ASIO drivers basically double your roundtrip latency.
I try not to make suggestions for features that are completely selfish, because it's not my intention to ask developers to waste their time on something that won't help anyone else... But, if I could have individual deck outputs in addition to master/cue outputs while using Cross' internal mixer, it would help me a lot. I don't know if it would ever make sense to anyone else, but perhaps there's a way I can get "under the hood" without much effort to make this happen?
