Overview

tune is planned to be part of a larger ecosystem for microtonal software in Rust.

Current projects relying on tune are:

• tune-cli: A command line tool with live-retuning capabilities
• microwave: A microtonal modular waveform synthesizer
• fluid-xenth: A microtonal soundfont renderer

Demo

• The Bedoginning (17-EDO)
• Don't Take Five (16-EDO)
