CodeKlavier
Live coding with the piano as interface.
An open source project by Felipe Ignacio Noriega and Anne Veinberg.
CodeKlavier development started in April 2017 and currently has five modules (newest on top):
- ARquatic (A CodeKlavier Augmented Reality experience!)
- Ckalcuλator (Lambda-calculus with the piano!)
- Hybrid (switching between the first two prototypes and includes a custom code display via udp sockets)
- Motippets (coding via pianistic gestures/motifs)
- hello world (proof of concept prototype, with 1-1 mapping of piano keys to alphanumeric characters)
More information about the specific prototypes can be found in their respective directories.
Latest
CodeKlavier made two videos for this year’s HashiDays event. The first is ARquatic and the second uses the Motippets module to code in Mercury. With thanks to Simon Kelaita and Patrick Borgeat for the audio and video editing respectively.

Goals
Equipment
-
An acoustic-MIDI piano such as a Disklavier, any piano fitted with a silent system or an acoustic intrument in combination with a MOOG piano bar or other MIDI keyscanner. We use a MIDI KeyScanner developed by Andrew McPherson and his team at Queen Mary University of London. If an acoustic-MIDI piano is not available, any 88-key MIDI keyboard will suffice providing this instrument is of suitable sensitivity for the pianist.
-
MIDI interface (if not integrated in the piano)
Libraries
Install with pip3
- python-rtmidi
- pynput
- sphinx
- numpy
- python-osc (if you want to use the AR module and Caffeine Extension)
- websockets (idem)
Run pip3 install -r requirements.txt
to install the required libraries.
Modules
For this version please add the CodeKlavier directory to your sys.path so the CK modules are recognized
You can run the setPythonPath.sh
every time you start a new shell (type . setPythonPath.sh
- not the dot-space before the command), or put the following lines in your ~/.bash_profile
or ~/.bashrc
or equivalent add the following lines (make sure you have the correct path!):
# Modules for the CodeKlavier
PYTHONPATH="/path/to/your/codeklavier/project/folder:$PYTHONPATH"
export PYTHONPATH
As an example, the path to the Codeklavier in my system looks like this:
` PYTHONPATH=”/Users/narcodeb/Development/Repos/codeklavier-python/CodeKlavier:$PYTHONPATH” `
Extensions
There are a number of different code output extensions for the CodeKlavier. The loading ini file for these can be found in the CodeKlavier-Extensions repository[https://github.com/codeklavier/codeklavier-extensions]. You will need to download/clone this directory in order to run CodeKlavier.
If you are interested in collaborating on an extension for the CodeKlavier, don’t hesitate to get in touch.
Currently, outpute extensions exist for SuperCollider, Mercury, JavaScript, Augmented Reality and Hydra.
Test run
After installing the libraries, plug in your midi device and run the miditest by python3 miditest.py
. After you complete the setup and configuration, you will see the midi messages on the screen. After that run codeklavier.py -p hybrid -i base.ini (be sure to change the directory too match your setup Try playing an upward C major 3 note arpeggio starting on middle C. If everything works, your test is complete and you are ready to explore CK!
