There's a few Control Surface mavericks here, and I'm not one of them. But I'll post this link to a ten-year old thread:viewtopic.php?f=1&t=75093&start=20
From time to time, someone on LPH remarks with surprise that there are no key commands for track selection. Agreed, but bear in mind that projects with fifty, eighty, one hundred tracks is not surprising, as I view other people's work on forums and tutorials. That'd be a lot of KC's, although like markers, maybe Apple could give us KC's for the first twenty tracks or so.
As for the link, I read it nostalgically. It helped me solve the problem, thanks to fader8 and shivermetimbers... wherever they are, thanks again. I agree with JakobP: I don't think Track Select is possible without a controller surface. I use a Nanopad -- sixteen buttons, sixteen tracks. I guess I'm a minimalist. But the Nanopad needs to be set up as a Control Surface.
To repeat, I'm not an expert. But the fact that there's no pre-existing control setup for your ProMix 01 does not mean it cannot be used as a control surface. My Nanopad was created with the Logic Control preset. The port assignments are what's important. The icon looks like the MCU, but it's listening to the Nanopad.
