If you run NPM and everything else, you will be able to send MIDI messages from the file to your synth.
But, as it's said on the bottom of the page:

NOTE: not every MIDI message is understood by every MIDI device!

Thank you for responding me as soon, Sema!

But It changes something If I run NPM and the other procedures once there is a MIDI message which my controller keyboard does not respond? Is that one utility from these procedures?

Dearly,

I use a controller USB keyboard and a DAW, the one Pro Tools 10.3.9 HD, and in my DAW, the MIDI message Channel Coarse Tuning apparently did not respond, although the one Channel Fine Tuning has done It.

Then, I have my question, If when they were supplied the requirements like running NPM install and other procedures, If then the MIDI message Channel Coarse Tuning shall answer.

I would like to make manually a Pitch envelope and I believe I executing Channel Coarse Tuning or some other MIDI message in my DAW, I could made It thus.

I think If I run NPM and attend the other procedures to execute MIDI files, I could get Channel Coarse Tuning working.

This NPM and the other procedures to execute test MIDI files work only for synthesizers or either too for controller USB keyboards?

NPM has nothing to do with MIDI.
It just installs the dependencies to run the node.js application.

Then, neither NPM nor Node JS may become the ambient of the computer proper for to execute MIDI files, not It is?

Then, even that I install Node JS and NPM and do everything else, certain MIDI messages won't respond, not It is?
