Control the Behringer X32 via WiFi using ESP32, e.g. as a stompbox
| control | OSC example | comment |
|---|---|---|
| mutes | /ch/01/mix/on,i |
LED state can be reversed |
| mute groups | /config/mute/1,i |
|
| faders | /ch/02/mix/09/level,f |
|
| snippets | /load,snippet i |
- one-way (just send) - in case we don't want to hog the bandwidth
- two-way (receive confirmation and update LED)
- monitor battery voltage, and flash GPIO LED if low
- long press button (for secondary function, e.g. variation of button)
- very long press button (to prevent accidental presses, e.g. major snippets)
- more than one widget can monitor the same GPIO button (e.g. short press and long press; short press event will be generated even if long press)
- indicate when battery nearly full
- excess power wasted trying to reconnect to WiFi if unable to connect (extra 70mA approx)
- battery voltage divider may drain battery
- WiFi password is hardcoded
- short press button event will be generated even if long press
- X32 echoes
/load snippetbut does not say which snippet - battery power switch disconnects battery (i.e. cannot charge if 'off')
- battery-full indication turns off when my ESP32-Lolin stops charging the LiPo
- subscribe vs xremote? subscribe gives stream of data even if no changes
2023-03-04initial draft2023-03-13about as much can be done now without actual hardware2023-04-06first site release
- test implementation of MIDI output; does MIDI SysEx method accept float?
- investigate - does actual X32 echo mute, fader, mutegroup?
- indicate battery level at start-up
- find other way to save energy usage if cannot connect to WiFi (WiFi.disconnect doesn't seem to stop the process)
- have a MIDI-only payload
