Module src.backends.fluidsynth.backend_controls
Fluidsynth backend controls for MIDI track management.
Provides functions to start, stop, and advance playback by sending TCP messages to a Fluidsynth-compatible server, and a static “help” dump loaded from disk.
Functions
| togglePlayback (host, port) | Toggle playback state. |
| beginSong (host, port) | Start playback of the current song (Tab). |
| endSong (host, port) | Advance to the next song in the playlist (Internal FluidSynth skip). |
| nextSong (host, port) | Force-kill the process to trigger the Thread to iterate to the next file. |
| send_message (message, host, port) | Send an arbitrary FluidSynth command. |
| getHelp (host, port) | Retrieve the static help text. |
Functions
- togglePlayback (host, port)
-
Toggle playback state.
If currently playing, sends “player_stop”; otherwise sends “player_cont”.
Parameters:
- host
- port
- beginSong (host, port)
-
Start playback of the current song (Tab).
Sends “player_start” and “player_cont” to ensure playback begins
even if the sequencer was previously stopped or the app was frozen.
Parameters:
- host
- port
- endSong (host, port)
-
Advance to the next song in the playlist (Internal FluidSynth skip).
Sends “player_next” after pushing a “clear” control message.
Used for Shift+Return to stop MIDI but keep process alive for live feedback.
Parameters:
- host
- port
- nextSong (host, port)
-
Force-kill the process to trigger the Thread to iterate to the next file.
Closes the TCP socket first to ensure the OS releases the port.
Used for Return to advance the Lua-level playlist.
Parameters:
- host
- port
- send_message (message, host, port)
-
Send an arbitrary FluidSynth command.
Parameters:
- message
- host
- port
- getHelp (host, port)
-
Retrieve the static help text.
Parameters:
- host
- port
