Explore musical tunings and create synthesizer tuning files for microtonal scales.

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
