Miconau (MIDI controlled audio player)

A audio player that is controlled via MIDI note-on events. On startup, the application will scan your audio library and assign every album to a white key on the keyboard. You can control the audio with the black keys. Uses mpv under the hood which can play a lot of audio file and stream formats.

Usage

Make sure mpv is installed and in PATH. Windows is not supported. Make sure, error.wav is in the same folder as the executable miconau.

cargo run --bin miconau -- --library-folder [PATH_TO_LIBRARY] --streams-folder [PATH_TO_STREAMS] --midi-device-index [MIDI_INPUT_DEVICE_INDEX] --start-octave [START_OCTAVE] --output-device [AUDIO_OUTPUT_DEVICE] --mpv-socket [MPV_SOCKET_PATH]

Example:

cargo run --bin miconau -- --library-folder /mnt/usb1/Music --streams-folder ~/.config/miconau --midi-device-index 1 --start-octave 4 --output-device alsa/plughw:CARD=Audio,DEV=0

Streams

Streams are configured separately from the music library. Point --streams-folder at a folder containing a streams.txt, and the streams in it are assigned to the lowest white keys, below the albums. The argument is optional: without it, the white keys start at the first album.

streams.txt holds one block per stream, separated by blank lines. A block is the name, the URL, and optionally the file name of a logo:

Radio Example
http://example.com/stream.mp3
example.svg

Another Station
http://example.org/live

Logos are SVGs in a logos/ folder next to streams.txt, and are shown in the web UI:

~/.config/miconau/
  streams.txt
  logos/
    example.svg

List available audio devices

Use mpv to list available audio devices:

mpv --audio-device=help
