Suits MIDI-capable studio consoles, button panels and class-compliant USB MIDI controllers.
| Control | Guidance |
|---|---|
| Device | Select the MIDI input presented by the controller, console or USB MIDI device. If no inputs are listed, verify the device in Windows and restart BroadcastLogger after connecting it. |
| Channel | Choose the transmitting MIDI channel, or any while testing. MIDI channel numbering displayed by hardware may begin at 1. |
| Note / CC | Enter the note number or control-change number to monitor. 60 is commonly known as Middle C when used as a note. |
| Run-on | Adds a short tail after the release, Note Off or zero-value control state so the final audio is retained. |
Basic Arduino example
Use a board that can appear as a class-compliant USB MIDI device, such as many Leonardo, Micro, Pro Micro or native-USB boards, with a compatible MIDIUSB library. This example sends Note On 60 while the button is pressed and Note Off 60 when released.
#include "MIDIUSB.h"
const int pin = 2;
bool lastState = false;
void sendTrigger(bool on) {
byte status = on ? 0x90 : 0x80;
midiEventPacket_t e = {byte(status >> 4), status,
60, byte(on ? 127 : 0)};
MidiUSB.sendMIDI(e); MidiUSB.flush();
}
void setup() { pinMode(pin, INPUT_PULLUP); }
void loop() {
bool on = (digitalRead(pin) == LOW);
if (on != lastState) {
sendTrigger(on); lastState = on; delay(25);
}
}Select the Arduino MIDI device, choose channel 1 or any, and set Note / CC to 60.
Some basic Uno or Nano boards do not present as native USB MIDI devices without additional firmware or hardware.
