Send coarse NRPN messages from TouchOSC

General Approach

For synths that use CC-over-NRPN (like the Circuit Tracks), assembling NRPN messages is pretty simple in a script:

function sendNRPN(ch, MSB, LSB, val)
  -- nrpn address msb
  sendMIDI({ 176 + ch - 1, 99, MSB })
  -- nrpn address lsb 
 sendMIDI({ 176 + ch - 1, 98, LSB })

Recording 4k 4:2:2 from Brio 4k In Linux using FFMpeg

Turn auto-exposure off, set absolute exposure to a low level and use gain to compensate for low light if needed. E.g.:

v4l2-ctl -d /dev/video2 -c exposure_absolute=400
v4l2-ctl -d /dev/video2 -c gain=110

# check with
v4l2-ctl -d /dev/video2 -L
