Subscribe not to miss it
 
Spice is a high-performance 4-in / 4-out Eurorack digital platform built for quadraphonic sound design and DC-coupled utility work. 
 
At launch (Phase 1), Spice ships as a quadraphonic wavetable phase‑modulation oscillator with global bitcrush and waveform selection. 
 
With a 16‑bit / 50 kHz architecture and full DC-coupling across all four I/O channels, it handles both audio and CV across all channels.
 
Under the hood, it is a platform designed to grow through firmware updates.
 
Current engine (Phase 1)
- Quadraphonic phase‑modulation (wavetable) engine
- Global bitcrush
- Waveform selection
 
Platform hardware :
- 4 inputs / 4 outputs, all DC-coupled
- 16‑bit / 50 kHz
- RP2350
- 8 MB RAM
- SD slot (wavetables + patch state loading planned)
- Stereo output
 
Roadmap (planned firmware expansions)
- Oscillator engines: Exponential V/oct, Scale Mode, Binaural Beat Frequency
- Modulation & utilities: LFOs, Envelopes, DC-coupled CV processing
- Buffer-based effects: Multi-head delays, buffer manipulation (using 8 MB RAM)
- Advanced features: User wavetables, patch state loading via SD Card
- Quadraphonic mixer (engine or dedicated firmware depending on resources)
 
Early Access (Founders Batch 1) Sold out
- 15 units only
- 170€ netto in Phase 1
- Price scales through a 6-phase roadmap toward a 370€ netto final target as engines/features are added
