NRPN function example

[Taurar]

This library is incredibly versatile and much appreciated!

I'm an beginner and I'm having trouble figuring out how to use it to send out NRPN values using the NRPN function in the library. Google has little useful information and I have not seen any examples using e.g. beginNrpn() and sendNrpnValue()

Would it be possible to post a short simple example on how to send out NRPN, for example in response to CC's?

Thanks!

You can read more about RPN/NRPN here:

The following example shows how to listen to RPN/NRPN, but because of their complexity, it's not built-in the library, and how to send them:
https://github.com/FortySevenEffects/arduino_midi_library/blob/master/examples/RPN_NRPN/RPN_NRPN.ino

The key part for sending is at the end:

// Send a RPN sequence (Pitch Bend sensitivity) on channel 1
const midi::Channel channel = 1;
const byte semitones = 12;
const byte cents     = 42;
MIDI.beginRpn(midi::RPN::PitchBendSensitivity, channel);
MIDI.sendRpnValue(semitones, cents, channel);
MIDI.endRpn(channel);
