mididings VS qmidiroute

You might want to have a look at mididings.

You can use MidiDings ( http://das.nasophon.de/mididings ) to perform such remapings, but iirc you can also change the notes send by the m-audio device. Last time I did this I used the m-audio software under wine to do the remaping.

If you have a raspberry pi (or you run Linux) to hand, then mididings can also do the same functionality and act as a converter for anything that has USB midi but not DIN/TRS

Great project! I've been using mididings for similar purposes. Main draw of this for me is customization in go instead of cpp. How would you say it compares otherwise?

Side note just in case: As a fader control, most softwares will expect a CC (control change) instruction, not a Velocity from a Note, with a Midi Channel from 1 to 16, a Control number from 1 to 128 and a Value (the changing part as you move the fader) between 0 and 127. If your hardware isn't configured like this, you can use qmidiroute to translate the signal from your device into something useable by the software.

I use qmidiroute on Archlinux to translate midi output from my interfaces to specific midi input for lighting software (like changing a CC to a note, or tweaking velocity values).
