Hi there folks. I have some keyboards that I want to add some custom controls to. They include all four of the Yamaha Reface series as well as a Casio CDP200R and an Alesis Vortex 2 Wireless keytar. I've been working on putting these all together into one big workstation for playing some progressive rock style synths live. The audio is running through a Tascam Model 12 mixer so I have the audio covered. To link them all together, I've got them all connected with USB MIDI to a Raspberry Pi Zero running Raspberry PI OS with this script here: https://github.com/dmessent/pi-midi-host-no-bt/tree/main/rpi-readonly That's pretty good if all I want is any key I press on any connected device to get echoed to all of the others. But what I actually need (and what I'm writing this mailing list for advice on) is some more advanced MIDI connectivity between these devices. I want to be able to, for example, set the Casio to control the Reface CP while the Vortex controls the Reface DX or swap that around without needing to unplug and replug cables. Normally, you would expect to be able to configure which MIDI channel each keyboard listens on for to do that, but Yamaha, in their infinite wisdom, has elected that all the Reface keyboards only work on MIDI channel 1. This means I need my MIDI host computer to route the MIDI messages. In addition, I would like to be able to send and receive synth patches as SysEx MIDI messages from the Reface keyboards to the micro SD card. (having the file system set to "read only" any time I'm not actually saving files) And I would like to be able to set up combinations of MIDI signal routes and patches as "songs" I can load up real fast for live playing. My thought has been to add a touchscreen to the Raspberry PI Zero and write a small GUI app to handle this. But I'm not entirely sure where to start. Maybe it could launch ALSA Patch Bay to do the routing, but what would it launch to send the SysEx MIDI messages for the patches? In particular I'm thinking to store all of the thousands of patches from the "Yamaha Reface DX Legacy Project" on the SD card so being able to quickly navigate lots of patches and to send and receive them real fast would be critical for this application. I'm a programmer so I'm thinking of making it myself if there isn't an app already in existence which will do all this. I am thinking of making it be a simple GUI that runs directly on Linux with no desktop environment under it and ABSOLUTELY NO NETWORK CONNECTIVITY required for normal operation since I want to be able to rely on this for playing live. I'd really appreciate any advice on what to do for this.
