From the project
Digital east coast style synth heavily inspired by the Buchla Easel based on the Daisy Seed.
firmware version 0.1 | hardware version 1.0
WEASEL is a digital synthesizer inspired by the iconic Buchla Music Easel, built around the Daisy Seed platform. It features a virtual patch bay that simulates a modular experience, allowing you to route modulation sources to destinations through an intuitive button matrix interface.
- Complex Oscillator with sine wave and morphable waveform (saw/triangle/square) - Modulation Oscillator with sine, triangle, saw, and square waveforms - FM/AM Modulation between oscillators - Wavefolder for complex timbre shaping - Dual-channel Low Pass Gate (LPG)…
