Currently debating dropping the touchscreen from the setup to enable a smaller footprint and an easier layout on a pedalboard.
In my big recording setup I currently travel with an iPad for controlling my Behringer X18, so using something like this to control reaper wouldn't be a stretch.

Today I tried out a cheap USB interface with my Reaper Pi, and it worked!
It was a noisy affair, but that's down to it being a rubbish interface. Next step is to try out another interface with a better quality input/output and go from there.

I've spent far too long looking at Cyberdecks on HaD and Reddit, I think. It's influencing my decisions with projects like this. It's not a bad thing. Ha ha ha!
One of the main issues I've had with this project is space utilisation; fitting two separate Pi systems and still having enough space for a foot controller with plenty of controls for the two systems.
Cyberdecks always seem to have a screen mounted off-centre on the back of the keyboard, and it creates space for a fair sized keyboard input, so I'd like to explore the same here.
To that end, I'd like to look into mounting the Pisound and a much bigger enclosure for footswitches for it, then look to mount the Pi touchscreen setup to the back of the pedalboard, using two bolts through the pedaltrain board and another two through the footswitch enclosure.

This requires some planning out.
Once I have mounted the Pi's to the pedalboard I need to measure the space left for the enclosure:
This will determine the amount of buttons and functions I can fit into the box.
Reaper Pi - essential controls:
Channel selection (two buttons? Or an encoder?)
Arm track to record (button)
Record / Stop (button)
Desirable: mute/solo/undo buttons. Could be added as held button press features.
Pisound - essential controls:
Pedalboard up/down (two buttons)
3-4 effect switches (with LED feedback to show on/off)
Analog inputs broken out to trs jack's for adding expression pedals.
I2c breaking out for possible extension button boxes to be added.
Research to be done:
Gut instinct is to run two Arduino Pro Micros as co-processors for this to give two native USB ports out. One used as a usb midi input for the Pisound, and the other as a usb midi device for shortcuts in Reaper.
I've picked up a Raspberry Pi Pico recently, and running Circuitpython on that also allows for native USB use. They're really cheap, so may also make for good choices for this.
Other options: run a software serial port out to a hardware midi jack and send midi data to the Pisound via the midi jack, dropping the need for dual controllers.
If there's going to be a network established between the two Raspberry Pi boards there's a shout for using an ESP8266/ESP32 board to send wireless MIDI, perhaps.
There's even a shout to use a Pi Zero in USB ethernet gadget mode to share one of the Pi's network connection.

Just a quick think-out-loud segment, here.
My current plan is to run mic/instrument into the Pisound, then split the stereo output into a direct mono out for live performance and the other mono out to the Reaper Pi; itself sporting a little usb interface to get the audio in. I have a JustBoom Amp/DAC HAT I could add to the Reaper Pi, to give me options of a decent headphone out for monitoring recording/playback tracks and some RCA outs and speaker connections some interesting use cases.
Over on another forum I am tracking a thread discussing the possibily of capturing audio on the Pisound Pi itself; if this turns out fruitful there may be a good argument for running a network cable between the two Pi's and having a setup that allows for dragging clips from the Pisound into Reaper. This network connection would also allow for the Reaper Pi to open up the Pisound virtual pedalboard interface for on the fly configuration.
