Raspberry Pi Piano Player AI

This is code for providing an augmented piano playing experience. When run, this code will provide computer accompaniment that learns in real-time from the human host pianist. Then the host pianist stops playing for a given amount of time, the computer AI will then improvise in the space using the style learned from the host.

Try it

1. Get a MIDI-enabled keyboard and two-way MIDI adapter
2. Get a Raspberry Pi (however, a Windows / Linux / OS X computer should also work) and connect it to the MIDI keyboard.
3. Build latest version of libportmidi (if your using Mac just do brew install portmidi, if Windows just Download it))

sudo apt-get install cmake-curses-gui libasound2-dev
git clone https://github.com/aoeu/portmidi.git
cd portmidi
ccmake .  # press in sequence: c, e, c, e, g
make
sudo make install

4. Install Go.
5. Install rpiai-piano:

go get -v github.com/schollz/rpiai-piano

6. Add export LD_LIBRARY_PATH=/usr/local/lib to your .bashrc. (Unnessecary if you did not build portmidi). Reload bash source ~/.bashrc if this is the first time.
7. Play!

rpiai-piano

TODO

• External script that will start/stop piano based on plugging in Midi
• Put links to code on Youtube videos (link to tree)
• If a config file is not present, use default values and create one for next time (and send a message to the user)
• Add a new button for reseting the system
• Add a function for shutting down
• Add command line functions
