Programming for MIDI controllers
@jordanorelliTuesday, August 20, 13
This is an EWI.
Tuesday, August 20, 13
An EWI does not make sound.
Tuesday, August 20, 13
It only makes data.
Tuesday, August 20, 13
It is a data horn.
Tuesday, August 20, 13
The data that the EWI makes is MIDI.

The EWI sends MIDI messages to a synthesizer.Tuesday, August 20, 13
MIDI
The synthesizer is just a program. It was free.

MIDI
The synthesizer sends sound to the speakers.

Tuesday, August 20, 13
You can send MIDI messages anywhere you
like.
Tuesday, August 20, 13
That is your right as a programmer.

I like to send MIDI messages to Processing...
Tuesday, August 20, 13

... and have Processing generates
graphics.

You can use the synth and Processing at the same
time.

This is my Launchpad.
Tuesday, August 20, 13
It also sends MIDI messages.
Tuesday, August 20, 13
It sends MIDI messages when you push its
buttons.
Tuesday, August 20, 13
Additionally, it can receive MIDI messages.
Tuesday, August 20, 13
Sending MIDI message to the Launchpad can turn
lights on and off.

I like to send MIDI messages to ChucK...
Tuesday, August 20, 13
MIDI
... and have ChucK generate sound.
SOUND
Tuesday, August 20, 13
ChucK is a strongly timed language. “one second” is always the same amount
of time.
Tuesday, August 20, 13
Since rhythm is a function of time, ChucK is an excellent keeper of
rhythm.
Tuesday, August 20, 13
Programming rhythm means programming time
itself.

(demo)
Tuesday, August 20, 13
We can also send OSC messages from ChucK to
Processing.

Tuesday, August 20, 13
...and have Processing generate graphics.

We can generate the sound and the graphics at the same
time.
