Rust Synthesizer with GUI

Software synthesizer programmed in Rust using crates rodio for audio playback, minifb for handling of user input and image for sprite rendering. All assets are made by me using Aseprite.

Requirements

• Rust

Cargo dependencies

• rodio
• minifb
• image

Running program: Cargo

The shell script 'up' builds and runs our application by executing the following:

1. cargo build
2. cargo run

Running program: x86 executable for Windows

One may also run an executable directly. This has been compiled for target 'x86_64-pc-windows-msvc' utilizing 'cargo build --release'
