SoyBoy SP - A GameBoy instrument

I want to do some chiptunes on GNU/Linux.

Edamame is the Humboldt penguin living in Tobu Zoo.

Overview

SoyBoy SP is a VST3 instrument plugin to generate some GameBoy-like sounds. It has some basic features below:

• Three oscillator modes (square wave, noise, wavetable)
• A 32-samples 4bit wavetable oscillator
• A linear envelope generator
• A frequency sweeping to bend the pitch automatically
• A stutter, it's like a note delay

Additionally, SoyBoy SP has these features:

• Can be polyphonic; you can choose a number of voices (1 ~ 6)
• Pitch bending with MPE (MIDI Polyphonic Expression)

See the website (Japanese ver. here) to know how to use. o

Install

GNU/Linux

Build

There is no binary distribution. You can build SoyBoy SP by the instructions below:

1. Install Rust toolschain
2. Install depentent libraries
   • apt install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libspeechd-dev libxkbcommon-dev libssl-dev
3. Clone this repository
4. Run ./build_vst3_linux.sh --release

Install

After doing that instruction, the directory soyboy-sp.vst3 will be created in the path target/release in this repository. The directory is the VST3 plugin. On GNU/Linux, VST3 plugin is a directory.

Windows

For the official binary distribution, see the BOOTH page.

To build it, install Rust programming language and run build_vst3_windows_release.ps1. A directory soyboy-sp.vst3 is created in target/release and this is a VST3 plugin.
