The HAARP is an FV-1 based digital polyphonic pitch arpeggiator.
Includes 24LC32A EEPROM with HAARP algorithm preloaded.
New Features! (2019 Edition)
- 8-position rotary switch for program selection
Program selection is now achieved with a 16mm 1P8T rotary switch instead of a standard potentiometer. This means better tactile feedback, aligning graphics with the switch positions will be more reliable, and no more need for the ATTINY microcontroller!
Controls
- Rate – Controls the speed of arpeggiation
- Step – Sets the number of steps in the arpeggiation pattern
- Mode – Sets the arpeggation pattern
- Wet – Adjusts the wet signal level
- Dry – Adjusts the dry signal level
- Direction (Toggle Switch) – Sets the arpeggation direction (Up, Alternating, Down)

Awesome sounding circuit. I’ve never played the EQD pedal, but the HAARP sounds exactly like the demos I’ve heard of the Arpanoid. Great job Bugg!

Added this behind a Boss SY-1 synth pedal and it’s perfect – no need to mess with software instruments and pull out the midi keyboard when I want synth sounds. Build was extremely smooth as well. Fantastic all around!
