The machine combined pre-existing products: the Omni, Odyssey, a Solina-esque string synthesizer unit, a phaser and a divide-down organ with ADSR envelope, and a 4075 24 db low pass filter into one box.

The synthesizer's 8048-based microcontroller uses battery-backed CMOS SRAM storage[1] to store and recall 16 sets of on/off decisions about which waveforms and modulations are turned on in each of the four sections, and lead intervals.

Using LEDs the player is visually directed to the sliders critical to the sound selected but their settings are not updated.

The top three octaves of the keyboard have a mechanical touch sensor that can either pitch bend or impact brilliance and filter.

Like all ARP synthesizers of this series (2800) its true character opens up with selective use of the optional foot pedals.
