Great! Yes, the meters' dynamics have a range of 128dB (-128->0).
Maybe one thing to validate is if the range has to be re-mapped after conversion to [-118...10] or if it actually is [-128..0]

You'll need to use OSC to read data. X/M32 do not send MIDI data (except for their restricted DAW mode)

Edit...

Or maybe with the proper setting wrt MIDI mode/remote:
Faders Tx/Rx on MIDI ch1, CC0-79, 0-127: Fader Level Value 95 = 0dB

Ha Ha!!! They finally got it right! :-) That's good, really, as it opens a larger set of devices to control the consoles. Note this was not necessarily an issue with WING as you can tell WING where to send its data (to which port I mean) as part of the sent OSC request; for ex /%10027/ch/1/mute will...

Hello, Just to let you know I (finally) moved to a 64bit dev/compiling environment. My programs will no longer work on very old platforms I guess. I used to compile using MINGW 32bits compilers, resulting in programs that would just work fine on all systems. I moved to the latest version of GCC, 64b...

You read the data from that fader, add or subtract the relative dB amount and send resulting the data back to the console.

I found this in my files... Maybe it can help: osc meter batches (all levels 16 bit signed short integers, resolution 1/256 dB): 0 (8) pre l, pre r, gate gr, comp gr, post l, post r, gate key, comp key; (single channel data) 1 (40) 16x ch pre, aux pre l, aux pre r, fx1 pre l, fx1 pre r, ... fx4 prel...

Done with version 0.23

Fully Agree!

... done in version 0.22. You can manage single or multiple MIDI pattern match with a flag in the .ini file
