End of chain stacked multi-fx and temporal control

Spagyros is a stereo end-of-chain performance processor running on the open Alchemy Lab platform. Nine effects, layered up to three at a time in series across a top, mid, and bottom slot:

• Top — DJ filter, morphing bit crush and saturation, riser
• Mid — parameter-controlled chopper, clock-synced beat repeat, and a Reverse/Slow time machine recording into a 32 MB stereo ring buffer — drag the playback head backwards, brake to a vinyl stop, or race ahead at catch-up speed
• Bottom — resonant phaser, echo, space

A panic mute (any two row buttons, or a trigger on the bypass jack) drops all three slots at once. Every pot records a looping parameter-lock modulation. All six CV inputs are live: per-slot depth, 24 PPQN clock, reset, and bypass trigger.

The hardware is field-programmable: six CV jacks configurable as in or out, front-facing USB-C for MIDI, micro SD, and an open source SDK. Load Echoa or any other Alchemy Lab firmware on the same module.
