'Pandora' is a bandpass filter/distortion processor, based on an unusual combination of power MOSFET transistors and vactrols. Voltage control is provided over the two sides of the filter, the gain, and the filter feedback. A wet/dry mixer is provided, also under voltage control.

A range switch is provided to drop the filter response several octaves, at which point the module becomes capable of synthesising percussion sounds when fed trigger pulses.

The module is 100% analogue.


Sound On Sound magazine (June 2024 issue) said

It crackles with character and attitude … It certainly calls to mind synths like the Korg MS‑20 … its growling, throaty character, something Pandora has in spades … in effect turns it into a capably gnarly drum synthesizer … something of a masterstroke … a range of percussion sounds that are smooth, crunchy and everything in between. Beautiful.

It was really fun finding the sweet spots—of which I found a lot—in Pandora's box of tricks
