Looks like Recotana finished work on the heartbeat controlled MIDI device, very cool! Interesting choice in sound patch for the demo video – emphasizes that man/machine contrast. Now we just need one more clip documenting a heart-pounding treadmill recording session.

That’s cool, but it looks like the program was playing a loop instead of actually triggering in real time off the pulse from the controller.
The loop looks like the synth sound attributed to the MIDI note the controller was “playing”. MIDI data does not naturally have a ‘sound’ attached to it like an analog audio signal. MIDI data is loosely equivalent to digitized sheet music in a way- the MIDI can be played back with a hardware or software synthesizer to connect audible sounds to the data. The same MIDI data can be played back with different orchestrations- guitars, pianos, voice effects, or discrete sound samples like what’s illustrated above.
