0.2.x

0.2.7

  • Fixed: Note-off events at the end of a track are sometimes not detected during export
  • Fixed: Panic when decaying audio if the output buffer exceeds the length of the decay buffer.
  • Allow alphanumeric input in --events events.txt.

0.2.6

  • Fixed: If you let all notes in your music play (as opposed to stopping in the middle), it frequently becomes impossible to play or add new notes.
  • Added a build env variable: Set CACOPHONY_BUILD_DATA_DIR to set the default path to the data directory.

0.2.5

  • Dropped MacOS 11 builds on itch because there isn't a GitHub workflow runner anymore.
  • Added MacOS 14 builds to tests and itch uploads.
  • Added Ubuntu 24.04 builds to tests and itch uploads.
  • Fixed: Crash if a Channel Pressure or Program Change message is sent from a MIDI controller.
  • Fixed: Various TTS race conditions.
  • (Backend) Added some more tests
  • (Backend) Bumped ureq version (fixes a security warning)
  • (Backend) Bumped Cargo.lock versions (fixes a security warning)
  • (Backend) Removed audio/Cargo.lock (fixes a spurious security warning)
  • (Backend) Added tests for TTS

0.2.4

  • Fixed: If note is played via a qwerty key press, and then an octave is changed via a qwerty key press, there won't be a note-off event.
  • Fixed: Cacophony can't found files (saves, soundfonts, etc.) if the file extension contains uppercase characters.
  • Fixed: ChildPaths sometimes doesn't set the correct directory when moving up a directory.
  • Fixed: It's possible to add notes while the music is playing.
  • Fixed: When you save a new file, the panel will list children in the save directory's parent folder.
  • (Backend) Fixed clippy warnings for Rust 1.78
  • (Backend) The GitHub workflow for building Cacophony now uses the latest version of Rust.
  • (Backend) Added tests for ChildPaths.

0.2.3

  • Optimized text and rectangle rendering, which reduces CPU usage by around 5%.

0.2.2

  • Fixed: There was an input bug where the play/start key (spacebar) was sometimes unresponsive for the first few presses. This is because audio was still decaying from a previous play, meaning that technically the previous play was still ongoing.
  • Fixed: When a new file is created or when a new save file loaded, the app didn't reset correctly.
  • Fixed: If you try to play music and there are no tracks or no playable notes, the app starts playing music and then immediately stops.
  • Fixed: If you're playing music and then load a save file, the save file can't play music because the synthesizer still has MIDI events from the previous music.

0.2.1

  • I replaced the default qwerty bindings for note input with a more "standard" layout. This information is stored in config.ini, so if you want the update, make sure to delete Documents/cacophony/config.ini if it exists (Cacophony will use the default data/config.ini instead).
  • The background of the export settings panel was the same color as the text, so that it just looked like a weird gray rectangle. I fixed it.

0.2.0

Cacophony uses a lot of CPU resources even when it's idle. It shouldn't do that! I reduced Cacophony's CPU usage by around 50%; the exact percentage varies depending on the CPU and the OS. This update is the first big CPU optimization, and probably the most significant.

These are the optimizations:

  • In audio, Synthesizer (which no longer exists) ran a very fast infinite loop to send samples to Player, and the loop needlessly consumed CPU resources. I replaced this loop with a bunch of Arc<Mutex<T>> values that are shared between Conn and Player. As a result of removing Synthesizer I had to reorganize all of the exporter code. There are a lot of small changes that I'm not going to list here because let's be real, no one reads verbose changelogs, but the most noticeable change is that Exporter is a field in Conn and is no longer shared (there is no Arc<Mutex<Exporter>> anywhere in the code). This change affects a lot of the codebase, but it's mostly just refactoring with zero functional differences.
  • In input, Input checked for key downs and presses very inefficently. I only had to change two lines of code to make it much faster. This optimizes CPU usage by roughly 10%.
  • A tiny optimization to drawing panel backgrounds. This required refactoring throughout render. I think that there are more tiny optimizations that could be made in render that cumulatively might make more of a difference.

This update doesn't have any new features or bug fixes. In the future, I'm going to reserve major releases (0.x.0) for big new features, but I had to rewrite so much of Cacophony's code, and the results are such a big improvement, that I'm making this a major release anyway.

0.1.x

0.1.4

  • Fixed: Crash when setting the input beat to less than 1/8

0.1.3

  • Added .flac exporting
  • Fixed: Crash when attempting to add silence to the end of a non-wav multi-track export. I don't remember why I wanted to add silence in the first place, so I've removed it.
  • Fixed: --events [PATH] argument doesn't work.

0.1.2

  • Added environment variables and command line arguments:
    • Add a save file path to open it at launch, for example: ./cacophony ~/Documents/cacophony/saves/my_music.cac
    • CACOPHONY_DATA_DIR or --data_directory to set the data directory
    • CACOPHONY_FULLCREEN or --fullscreen to enable fullscreen.
  • (Backend) Renamed feature flags ubuntu_18_20 and ubuntu_22 to speech_dispatcher_0_9 and speech_dispatcher_0_11, respectively
  • (Backend) Paths is now handled as a OnceLock
  • Added missing compliation requirements in README. Added compilation instructions for Debian 11 and 12.
  • Added this changelog
