Steam Deck/Windows/Reaper/Bluetooth mixing in car.

I previously expressed, elsewhere, the desire to run Reaper on the Deck and bring the device to the car to mix directly there via Bluetooth. Others have expressed similar ideas at various forums and were discouraged due to known issues with Bluetooth, including latency. Always assumed latency would be an issue, but not for mixing (except for timed automations?). Haven't been able to install in Linux, for some reason, so I put Windows on an SD card and went that route (my Native Instruments plug-ins/programs aren't on Linux, so that's another thing to figure out, later as well).
Huh. It works, and the latency isn't bad for adjusting levels and whatnot. Comments on a few forums had suggested otherwise. For monitoring while recording, probably not ideal, but if I wanted to record, I could just use headphones (the Deck has a headphone jack). The use of the touchscreen here, seems less than graceful. That's both due to the size of the sliders onscreen, which I can probably adjust and my use of the right hand to hold the phone taking the video, resulting in some awkwardness. Other interface options include the Deck's track pads and buttons, and an external foldable Bluetooth keyboard w/ trackpad which I ordered after watching and seeing it on the Windows install video. The music is a work in progress blues/funk thing from 2017, with only about 3 or 4 tracks. I'll need to test out a more fully realized song, using both of my hands, and during temperatures that don't require keeping my car in idle so I can have the AC on.
On the gaming front, Halo (Master Chief Collection) stopped working for some reason. It was never on the list of games that worked with the Deck, but it did, in single player mode, and now it doesn't. Will have to check around and see if that's happening to other folk. Started (re)playing Black Mesa (Half Life 1).
