MIDI Practice tool

I am trying to develop myself a small tool to improve my (beginner-level) sightreading. For that I want to use the MIDI integration of my piano in order to quickly check if I am doing it correctly.

usage

• in order for MIDI to work https must be used
• nginx doesen't seem to properly server the svg wihtout adding the mimetypes to the nginx.conf include /etc/nginx/mime.types;
