Solfege Core

Solfege is a Rust-native sampler and instrument runtime. This repository now contains the core libraries and host/format adapters only; the standalone app, egui UI, and GPU presentation layer have been removed.

The realtime engine is built from immutable prepared samples, bounded event and voice state, and mmap-first storage. Host integrations translate their events at the adapter boundary without adding UI or application-shell dependencies.

The same engine now also exposes a first-class physical backend. Construct a RuntimeInstrument::bowed_string(...) to render the generic bowed-string waveguide through the existing solfege-engine/solfege-voice path; sample instruments remain unchanged. Enable the optional fbmx feature to install the repository's pure-Rust fbmx-runtime performer/residual hooks.

Render a deterministic offline reference sequence with:

cargo run -p solfege-tools --bin solfege-render -- bowed-string bowed-string-reference.wav 8

The legacy OpenSampler sources remain under oldcode/ as a behavior and file format reference only. They are not members of the Rust workspace.
