DmxOut [DMX address 1-512], [DMX level 0-255]
For multipel channels simply add one per line
Setting level from a MIDI control
“APC40MKII Template” has an example for adjusting DMX channel 1 for Message “B0 32 xx”:
// DMX
// - Change the first number to adjust the dmx address
// - Uncomment for multiple dmx channel controls.
//
DmxOut 1, extvalue (0,255)
//DmxOut 2, extvalue (0,255)
If you want to limit the range of output, so say a max MIDI level outptus 100 instead of 255, just alter like this: extvalue (0,100)
