Hello, I'd call myself a very basic user musically however very experienced technically. I'm looking for a way to control where Jack output goes - mainly headphones and/or line-out (to amp and speakers). I have a single Jack output called "system" that hands over to ALSA and I need to use the alsamixer to control whether that goes to headphones, speakers or both, and at what volume levels.
I can use the command-line alsamixer but what I'd really like is something integrated, say that I could drop onto my patchbay (I use Carla) and control its sliders and buttons with my midi control.
The best graphical control I've found is qasmixer (of qastools) but it is sorely lacking the hardware integration I could get if I could control it over midi.
It'd be good to be able to control this from my Carla Jack rack.
I expect there's nothing like this, which surprises me as I don't see it as a "complex need". Perhaps I am doing it wrong, how do others approach this?
