Polarbear Effects Petrichor

Petrichor is a wildly fun lo-fi delay sequencer capable of fun pitch jumps and randomized delay sequencing. Set each step to a predictable time division, or use RANDOM mode to add some beautiful unpredictability to your delay sound. Petrichor is a beautiful delay playground, lo-fi sequencer and a wildly fun device to create with! Builder notes below:

This is an updated version of Petrichor:

MIX control is now split in two separate controls: DRY (clean) and WET (delayed) signal.
Larger enclosure: from 125B to 1590BB.
Minor sound adjustments.
Petrichor is a lo-fi delay sequencer pedal based on 2399 chip.

DRY controls the clean signal.

WET controls the delayed signal.

REPEATS controls the number of delay repeats.

DELAY controls delay time and sets the speed of the sequencer in quarter notes.

4 left toggles control the delay time divisions of the sequencer. Each LED indicates one of four sequencer steps. First LED always flashes with the tempo of the delay.

Fifth toggle controls the number of steps.

4 is normal mode in which all 4 sequencer steps are active.
3 will bypass 4th step of the sequencer.
SHUFFLE ICON activates RANDOM mode in which all 4 steps are active, but the sequence is random.
For activating the second RANDOM mode in which timing of the steps is more random and unpredictable, hold the TAP TEMPO footswitch when plugging in the power. Flashing LEDs on power up will indicate the RANDOM mode change.

Sixth toggle controls the duration of each sequencer step in delayed quarter notes.

Left footswitch is BYPASS.

Right footswitch is TAP TEMPO.
