- Brume is a desktop multi-timbral music machine with four synthesis engines (FM, Harmonic, Timbral, Granular) and a shared voice tail for coherent patches.
- It features a 10″ touch surface, one USB cable for multi-channel audio, bidirectional MIDI, and clock, requiring no drivers.
- Each synthesis engine has unique spectral change mechanisms: FM uses DX-style with six operators and per-voice envelopes, Harmonic uses Gaussian scanning, Timbral uses wave-multiplying, and Granular uses pitched grain clouds.
- The system includes MIDI support, modulation, a state-variable filter, envelopes, mixer, sends to delay and reverb, and a Lua FX slot for custom processing.
- Hardware is based on Raspberry Pi Compute Module 5 with off-the-shelf parts, running Raspberry Pi OS Lite with a Rust audio runtime, booting fast.
- It supports integration with DAWs like Bitwig, Logic, Ableton, and Reaper via USB, with planned per-part stems output.
- Reference MIDI controllers include Korg nanoKONTROL2 and Novation Launch Control XL, with customizable mappings and Lua scripts.
- Installation is via CLI (brumectl) on Raspberry Pi OS Lite, with updates over SSH, and the UI auto-scales to connected touchscreens.
