DIY MIDI Controller: BF-8 Build with Arduino
9This is the BF-8, a DIY MIDI fader controller I put together for interfacing with my DAW. It’s got 8 faders, toggle switches to mute tracks, a 4-digit 7-segment display, and a programming button. Big thanks to Notes and Volts for the FADR-4 inspiration—seriously, go check out their channel!
In the video, I cover:
-How it works with REAPER
-Programming faders, switches, and MIDI channels
-The build process (Arduino Micro clone, TM1637 display, CD4051 multiplexer)
-A quick look at the code (MIDIUSB, data smoothing, etc.)
-Some quirks and fixes, plus it’s Eurorack-ready (3U, 42HP)
If you want to build your own, the GitHub link below has schematics, code, and parts list. Interested in buying one? Drop me a message—available as a kit or pre-assembled. Let me know if you make one, I’d love to see it!
