MIDI Notes Input

Hi. I can connect my MIDI piano to Notch and get a couple control channels to react, but some only half-work and others don’t react at all. Is there a way to get MIDI note data into Notch to send the value to other nodes like the MIDI control channel data can do? I want to create something like this, which I made in d3.

Try using the Quantize node to round the data up, that might help a little if you play with it.
