Send a MIDI message of 1 to 3 ``bytes'' (without checking values) Midi2Max( status, fsr, 0 ) // send a MIDI ``note off'' message Midi2Max( status, fsr, 90 ) // send a MIDI ``note on'' message Temp += 50 // scale the value between 50 - 90 Serial.begin( 115200 ) // set the MIDI baud rateįsr = analogRead( fsrPin ) // read the input pin Void midi2Max( int cmd, int data1 = -1, int data2 = -1 ) midi2Max function declaration with optional arguments

Note that we need to perform our internal scaling with a float variable to avoid exceeding the limits of the int data type.

In another example with MIDI, we can control the pitch of the MIDI message using a sensor.

Void midi2Max( int cmd, int data1, int data2 ) Send a 3 ``byte'' MIDI message (without checking values) Midi2Max( status, 60, 0 ) // send a MIDI ``note off'' message Midi2Max( status, 60, 90 ) // send a MIDI ``note on'' message Serial.begin( 115200 ) // set the baud rate

If you need to manipulate the message values, then you can unpack them as shown in the previous example.

The midiout object in Pd only works for Linux, so we can use route and noteout objects instead, though this requires more careful consideration of the MIDI channels being used.

In Pd, the comport object is used to receive the serial stream.

In Max, the messages received by the serial object can be sent directly to the midiout object after conversion to a list of numbers.

From the Arduino, we can send MIDI byte values as space-separated integers. We can also send MIDI-like messsages from the Arduino to Max/MSP or Pd by slightly modifying the approaches above.Pseudo MIDI Messages from the Arduino to Max or Pd Next: MIDI Output from the Arduino Up: Serial Communication: MIDI and Max/MSP Previous: Interfacing the Arduino to Max/MSP
