How to read the controls
Names refer to the original Aurora panel. Shift + control means hold Shift while using that control. CCW / CW mean counterclockwise / clockwise. Selector colors are not the firmware’s running LED colors.
Stereo feedback-delay-network reverb. The original panel labels map to the
FDN overlay as follows:
Knobs and CV
| Panel knob / matching CV | Function |
|---|---|
| Warp | Pitch: modulation amount; CCW disables modulation |
| Time | Decay; short/comb-like CCW, near-infinite CW |
| Blur | Input Level: 25–150% by default |
| Reflect | Highpass: wet-signal high-pass filtering, increasing CW |
| Mix | Dry/wet balance |
| Atmosphere | Damp: damping increases CW |
Buttons and gates
| Button | Function |
|---|---|
| Reverse | Reverse incoming audio |
| Freeze | Hold captured audio |
| Shift + Reverse | Swap DSP order: reverb last ↔ reverse last |
| Shift + Freeze | Switch input-level range: 25–150% ↔ 0–150% |
Notes and sources
CVs follow the remapped controls; the guide specifies ±5 V and a 0.4 V gate
threshold for Reverse/Freeze. Left input normals to both channels without a
right input cable. Running LEDs use purple/gold, unlike the blue selector color.
Start with moderate Time and raise it gradually: high settings feed back.
