bandpass filter/distortion

'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.
