Stereo Dual-Delay
Echoa
Four delay lines total — two per stereo channel. Morph delay into reverb from first principles, from clean digital delay to smeared, textured reflections. Route the four lines in series, parallel, isolation, or spectrally. Presets, parameter lock on every pot, character engines, and more.
- Delay lines
- Four (2 stereo channels)
- Configurable up to 4x true multitap per line.
- Delay time range
- 1 ms – 16 s
- Karplus-Strong to long echoes. Max time selectable in settings: 2 / 4 / 8 / 12 / 16 s.
- Reverb Control
- Every delay line
- Craft reverbs by spectrally separating reflections.
- Routing modes
- Series · Parallel · Mono · Spectral
- Precisely control the four delay lines.
- Parameter lock
- Every pot
- Record up to 4 seconds of motion.
- Presets
- 16 slots
- Load and save finely tuned sound design.

I/O
Field Programmable I/O
The Alchemy Lab's six central jacks are firmware controllable between CV in and CV out — you can reshape the module's wiring in code and physically remap circuits with the SDK.
Light
Individually Addressable LEDs
102 RGB individually addressable LEDs let you visualize motion, position, modulation, or anything else your firmware needs to say.
Expansion
Expandable Interfaces
A rear SPI / I2C header opens the module to expanders, sensors, and companion hardware. Build your own peripherals against the same open SDK that powers the panel. Hermetic Modular expanders are coming soon!
Open Source SDK
Hackable
Down to the Silicon
The Alchemy SDK provides a powerful framework for leveraging all the conventions of Echoa and Spagyros — bring your DSP and let the SDK handle the UX. Or build your own from the open HAL.
