The LED Piano  

"The LED Piano" is a project that allows for and LED strip to interactively assist your piano playing using the Synthesia

About The Project

Inspired by: Onlaj's Piano LED Visualizer.

Main reason I chose to rewrite it from scratch was:

• Move to Python3
• Make the codebase useable (Onlaj's has 1 file with ~ 3000 lines)
• Maintain two connections (piano/synthesia) instead of 1 (synthesia)
  • This allows us to do cool things like mark notes red/white depending on if you play them correctly
• Make it more hands off. Plug it in and connect. The project handles reconnections of devices seemlessly so no more sshing to get things to work.
• Overall productionalizing that I felt the original repo was missing

Installation

1. Clone the repo

git clone https://github.com/GrahamMThomas/TheLEDPiano.git

2. Install required packages

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

3. Add midiusb.rules file

cp 33-midiusb.rules /etc/udev/rules.d/33-midiusb.rules
sudo udevadm control --reload
sudo service udev restart

4. Install rtpmidi

• Run and create a session. Name it whatever you want. Enable it. Ignore Bonjour errors
• Create a new Remote Peer (+ sign under directory). Chuck your PI address and use 5004 as the port
• Click connect and then turn on your piano (You have to reconnect rtpmidi everytime the piano turns off)

5. Open synthesia and make sure they are connected

• Set Key light to "Finger-Based" channel
• Uncheck all boxes under "Use this device for:" section

6. Get Device names and add to config.yaml

aconnect -l

Example Output:

client 0: 'System' [type=kernel]
    0 'Timer           '
    1 'Announce        '
client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 20: 'Clavinova' [type=kernel,card=1]
    0 'Clavinova MIDI 1'
        Connecting To: 128:1
        Connected From: 128:1
client 128: 'rtpmidi raspberrypi' [type=user,pid=1459]
    0 'Network         '
    1 'Maelstrom       '
        Connecting To: 20:0
        Connected From: 20:0

Here your piano device name is Clavinova MIDI 1 and synthesia is Maelstrom. Put these values into the config.yaml

7. Configure to run on boot

sudo cp pianoled.service /lib/systemd/system/
sudo chmod 644 /lib/systemd/system/pianoled.service
sudo systemctl daemon-reload
sudo systemctl enable pianoled.service
sudo reboot
