How to send a pitch bend MIDI message using arcore?

Question

I'm new to MIDI and started playing with an Arduino Leonardo and arcore. Based on the example code, I can easily send noteOn/noteOff/controlChange messages, but I can't seem to send a pitch bend message.

Having a look at this table:

0xE0 Chan 1 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE1 Chan 2 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE2 Chan 3 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE3 Chan 4 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE4 Chan 5 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE5 Chan 6 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE6 Chan 7 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE7 Chan 8 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE8 Chan 9 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xE9 Chan 10 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xEA Chan 11 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xEB Chan 12 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xEC Chan 13 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xED Chan 14 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xEE Chan 15 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)
 0xEF Chan 16 Pitch wheel range Pitch wheel LSB (0-127) Pitch wheel MSB (0-127)

I've tried to send a message like so:

MIDIEvent pitchwheel = {0xe0, 127,127};
MIDIUSB.write(pitchwheel);

but this didn't work and I'm not sure what I'm missing/doing wrong.

Any hints/tips will be helpful.

• CL.: Please show the working code to send a note-on message.

Answer 1

arcore creator Ralf Kistner provided the answer:

// The pitch bend value is a 14-bit number (0-16383). 0x2000 (8192) is the default / middle value.
// First byte is the event type (0x0E = pitch bend change).
// Second byte is the event type, combined with the channel.
// Third byte is the 7 least significant bits of the value.
// Fourth byte is the 7 most significant bits of the value.
void pitchBendChange(byte channel, int value) {
 byte lowValue = value & 0x7F;
 byte highValue = value >> 7;
 MIDIEvent event = {0x0E, 0xE0 | channel, lowValue, highValue};
 MIDIUSB.write(event);
}
