Cacophony is a minimalist and ergonomic MIDI sequencer. It's minimalist in that it doesn't have a lot of functionality MIDI sequencers have. It's ergonomic in that there is no mouse input and a very clean interface, allowing you to juggle less inputs and avoid awkward mouse motions.

Buy Cacophony (or compile it yourself).

How to compile

I compile Cacophony with Rust 1.74.0 for Linux, MacOS, or Windows. Below is a list of operating systems I've tested:

Linux:

• Ubuntu 18.04 i386 with X11
• Ubuntu 18.04 x64 with X11
• Ubuntu 20.04 x64 with X11
• Ubuntu 22.04 x64 with X11
• Ubuntu 24.04 x64 with X11

MacOS:

• Catalina 10.15.7 x64
• Ventura 13.2.1 Apple Silicon

Windows:

• Windows 10 x64

All platforms

1. Install Rust (stable)
2. Clone this repo

Linux

Debian 11

1. apt install clang cmake speech-dispatcher libspeechd-dev pkg-config libssl-dev librust-alsa-sys-dev
2. cargo build --release --features speech_dispatcher_0_9

Debian 12

1. apt install clang cmake speech-dispatcher libspeechd-dev pkg-config libssl-dev librust-alsa-sys-dev
2. cargo build --release --features speech_dispatcher_0_11

Ubuntu 18

1. apt install clang cmake speech-dispatcher libspeechd-dev pkg-config libssl-dev alsa
2. cargo build --release --features speech_dispatcher_0_9

Ubuntu 20

1. apt install clang cmake speech-dispatcher libspeechd-dev pkg-config libssl-dev alsa librust-alsa-sys-dev
2. cargo build --release --features speech_dispatcher_0_9

Ubuntu 22 and 24

1. apt install clang cmake speech-dispatcher libspeechd-dev pkg-config libssl-dev alsa librust-alsa-sys-dev
2. cargo build --release --features speech_dispatcher_0_11

MacOS

1. cargo install cargo-bundle
2. cargo bundle --release

Windows

1. cargo build --release

Set the data directory

Cacophony's default data directory is located at ../data. To set the default data directory at compile time, set the CACOPHONY_BUILD_DATA_DIR enviroment variable:

export CACOPHONY_BUILD_DATA_DIR=/usr/share/cacophony
cargo build --release

Tests

To test, just cargo test --all.

Sometimes when debugging, it's useful to create the same initial setup every time. To do this, you can pass input events in like this: cargo run -- --events events.txt

...where the contents of events.txt is something like:

NextPanel
AddTrack
EnableSoundFontPanel
SelectFile

How to run

You can run Cacophony like any other application or you can use Rust's cargo run to compile and execute.

Linux

There are two ways to run Cacophony:

1. Copy + paste data/ into the output directory (target/release/). Open a terminal in release/ and run ./Cacophony .
2. Instead of cargo build --release, run cargo run --release Include the --features listed above, for example cargo build --release --features speech_dispatcher_0_11 on Ubuntu 22

MacOS

There are two ways to run Cacophony:

1. After compiling, double-click Cacophony.app (located in ./target/release/)
2. cargo run --release This will compile and launch the application but it won't create a .app

Windows

There are two ways to run Cacophony:

1. Copy + paste data/ into the output directory (target/release/) and double-click Cacophony.exe (located in release/)
2. Instead of cargo build --release, run cargo run --release

Upload

Assuming that you are Esther Alter and you have the relevant credentials on your computer, you can upload the website and create itch.io builds by doing this:

1. cd py
2. py -3 build.py
