Thanks for the info! Definitely some interesting possibilities in there. However, since I already spent the money to get a Zynthian v5 kit and have it assembled, I’d be more inclined to either wait for the Zynthian OS to catch up to this use case or to try a different operating system on the Zynthian v5 hardware I already have than to purchase a new box.
I’ve mentioned before that I already have a Raspberry Pi Zero setup to just act as a MIDI host/router, which I explain in more detail in this post: Before I throw my Zynthian out of the window - #27 by BenMcLean
What I was really hoping for the Zynthian to eventually do for me – beyond the signal routing that the Raspberry Pi Zero can do – is to save and load presets for the Reface keyboards since, while they all accept MIDI presets, most of them don’t have any onboard memory and the DX’s onboard memory is very limited.
Before I knew the Zynthian v5 kit existed, I was doing a ton of research online to try to figure out how I could connect a touchscreen to a Raspberry PI Zero to make this simple MIDI host/router into a preset selection machine as well. But when I saw that the Zynthian v5 kit existed, I realized that this was probably the best way to get a small device with a touchscreen that I could potentially hack if I didn’t like the official OS for it. So if waiting for the Zynthian v5 to improve (and participating with testing and maybe even some development myself) doesn’t work out, I’d be more inclined to just swap out the Zynthian OS for a different OS that does what I need rather than to invest in more hardware which might also not do what I need. But even that would be a last resort in the case that the Zynthian OS doesn’t eventually work out.
