so my schematic is pretty simple for the MIDI Out; basically it's the standard setup as shown here:http://www.roguescience.org/wordpress/wp-content/uploads/2011/07/midiO.png
In fact, when I plug in to the M-audio UNO MIDI interface, I do indeed receive the incoming MIDI data from the arduino (the MIDI IN LED lights up when I change values from the arduino).
However, when I try to hook it up with Reaper in my computer, it's not communicating at all. I've checked that the MIDI interface is not the case because it worked when I hooked it up with a MIDI controller keyboard. However, I did noticed that when I hooked it up with the keyboard, the MIDI IN LED kept turning on and off continuesly
, where as with the arduino, it only lights up when I change a MIDI note number.
I did not used the MIDI library that the arduino has. Instead, I've modified from another source. Basically this is what is sending out from the Arduino:
void ProcessMIDIOut(byte cmdtype, byte val1, byte val2)
//bugging test purposes: to see what values the TX pin is sending out.
if (cmdtype == PITCHBEND)
Serial.print(0xE0 | (channel & 0xf)); // control change command ***Error here:: "As of Arduino 1.0 the "BYTE" keyword is no longer supported. Please use Serial.write () instead
Serial.print(val1 & 0x7f); // pb MSB 0-127
Serial.print(val2); // pb LSB 0-15 - TODO
else // All standard note and cc messages
Serial.print(cmdtype | (output_channel & 0xf)); // control change command
Serial.print(val1); // command
Serial.print(val2 & 0x7f); // val1 0-127
So for instance, when I call out the function:
ProcessMIDIOut(144, 86, 100)
Would that be enough to communicate with the computer?
I know that these are the values that are sending since I've hooked an LCD to display it
