Download Fontelle
Fontelle is a compact native audio workstation created for Linux users who work with SoundFont banks. It opens .sf2 files and treats their internal values as starting points, exposing loop points, envelopes, filters, modulation routes and mappings for direct editing and automation. The application bundles an arrangement view, piano roll, mixer, synthesiser, drum machine, autotune and plugin hosting into a single download.
The software includes a sampler, a hybrid synthesiser with hundreds of presets, a physically modelled drum module, and a complete mixing section with native effects. Audio recording, MIDI input, file import and offline WAV rendering are part of the package. CLAP and LV2 plugins load with their own editor windows, and project bundles keep audio and settings together.
Fontelle is produced by Fopull LLC under the MIT OR Apache-2.0 licence and is distributed without fees, accounts or telemetry. Version 0.1.0 is an early access release written in Rust, with Linux as the primary target and Windows and macOS builds generated from the same workflow. An optional update check is the only network request the program performs, and it can be disabled.
