From the vendor

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)

Specifications

• Designed for a 125B enclosure with top-mounted jacks
