Crazily advanced floppy music player for Raspberry Pi
Project description
The Floppi-Music project aims at creating a “crazily advanced” floppy music library for the Raspberry Pi, written in pure Python.
Motivation
Everyone is doing floppy music these days, and it really gets old and boring. However, Eike badly wanted to try floppy music himself, and of course I wanted to meet his desire. Our plan was to create the floppy music code in pure Python, and we wanted to use the Raspberry Pi to have a lot of high-level interfaces available.
The final goal is to build a “floppy music jukebox” for presentation at events and conferences.
Implementation / design goals
Our intention was to break loose from the low-level approach to floppy music controller programming and use modern paradigms in a modern language instead.
The floppy music engine is entirely multi-threaded, with a playback engine scheduling playback of notes for the various floppy drive threads.
The framework is designed so it can be easily extended or used as a library. For example, all recognized input formats are parsed by seperate functions and converted to an internal format suitable for playback by the engine. It is easy to create such parsers for any other (sensible) file format.
Wiring scheme
The wiring scheme for the Raspberry and floppy interfaces can be found in WIRING.txt.
What works
Parsing of MML (Music Macro Language) files, via MMLlib
Playback of 4 (or 8) simultaneous tracks
floppi-play command to play recognized, single files through the engine
What is planned (Roadmap)
Parsing of MIDI files
A webserver to select tracks and manage a playlist
An mpd-compatible network interface
Control through an LCD display and buttons on a controller
Self-tuning of floppy drives

Awards
The Floppi-Music project has won the following (more or less serious ;-)) awards:
“Coolest problem of the friggin’ month”-award in #python for “Floppy disk drives being out of tune”
