Sending Raw MIDI Data in Max (and Pure Data)

Sending out raw MIDI data in Max/MSP with [midiout] for system messages and other live control.

Here, I use the [midiout] object in Max to send individual “note on” and “note off” messages, using our knowledge of the MIDI protocol. We can then expand that to algorithmic MIDI control of sequences in the Arturia DrumBrute Impact, including adjusting the clock and the song position pointer for funky, chaotic beats.

The MIDI Protocol: System Messages

An overview of MIDI System messages and how they can support MIDI programming and synchronization in your studio.

I ran away from an explanation of system messages in my previous video on MIDI Messages, instead focusing entirely on channel messages. In this video, though, I’m back to talk about System Exclusive Messages, System Common Messages, and System Realtime Messages, and how you can implement them for additional musical control.
