This listing is for the SOMA Laboratory Utilities for Pulsar-23 (Turret), an expander for the Pulsar-23 and other analog synthesizers. It features eight touch-sensitive sensors, four switches with metal tongues, two photoresistors, and five format converters from 3.5mm jack to metal pins, with all patch points designed as metal turret posts for use with alligator clips.

The signal processing section includes a clipping amp VCA with two inputs, four linear VCAs each with normal and inverted inputs and an AC/DC selector switch (gain factor ×1 to ×25), and two diode VCAs for generating harmonic distortion. A Warp section (waveshaper) with curve and drive controls, four freely assignable attenuators, and two gate-to-trigger converters round out the set.
