It’s easy to send data from just one sensor or button on the Arduino to Max/MSP for further processing and routing to music applications. Take the following example, which reads a potentiometer from Arduino analog input pin 0 and sends this data to Max/MSP as a serial stream of bytes. This stream of bytes has a data range of 0 – 127, perfect for MIDI control applications.
Once the data has been received in Max/MSP, it can be routed to a ctlout object, thus allowing control of any parameter in any application that accepts MIDI continuous controller inputs.
