Tempest 1.0.0
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 distortion: low frequencies bypass the distortion through a crossover;
the high band is driven, filtered and recombined. Mix is not dry/wet.
Knobs and CV
| Panel knob / CV | Function |
|---|---|
| Warp | Drive, 1–100× |
| Time | Pre-distortion high-pass, 20 Hz–2 kHz |
| Blur | Algorithm variation |
| Reflect | Bipolar bias; center deadzone; reduced range in Standard mode |
| Mix | Crossover, 20–500 Hz |
| Atmosphere | Post-distortion low-pass, 20 Hz–20 kHz |
| Shift + Mix | Output trim, 0–2× |
Buttons and gates
Reverse advances algorithms; Freeze goes back. Shift + Reverse advances banks;
Shift + Freeze cycles Standard (green), tube (orange), odd/inharmonic (purple).
Hold Freeze 5 seconds without Shift to toggle cabinet simulation; three
white blinks confirm. Freeze gate holds an input sample; Reverse gate adds
octave-up rectification. CVs add to knobs (±5 V).
Reverse shows bank color; Freeze shows mode color. Arc LEDs show algorithm and
distortion level. Settings autosave after two seconds without changes.
