SOMA Pulsar-23 Utilities (Black)

The Soma Utilities is a set of auxiliary modules designed to expand the functionality of the PULSAR-23 drum machine and enhance compatibility with various CV (control voltage) devices, such as Eurorack systems and semi-modular synthesizers.

Features of Soma Utilities

Soma Utilities includes two modules: passive elements like switches, resistors, and capacitors, and active components such as amplifiers and waveshapers. The passive modules improve switching and control capabilities for the PULSAR-23, enabling greater flexibility in signal routing.

The amplifiers are available in both linear and non-linear types. Linear amplifiers increase the signal strength from external devices that operate at lower voltage levels to meet the PULSAR-23's input requirements. For example, it can convert a 5-volt output from a step sequencer to the 10 volts needed to trigger the drum modules or raise a 1-volt signal from a cassette tape recorder to the necessary 5 volts for standard audio input. Non-linear and controlled amplifiers, along with waveshapers, modify both the signal level and spectral content, distorting the waveform and adding harmonics, drawing from the early, elegant designs of transistor-based circuits.

Design and Build Options

Soma Utilities offers two distinct versions: one featuring PULSAR-23 style turret connectors for attaching alligator clips, and another version with screws instead of pins, also compatible with alligator clips, providing a more affordable alternative. Additionally, adapters are available for 3.5mm Eurorack mini-jacks.

The top panel and enclosure are constructed from printed circuit boards (PCBs), reducing production costs and making the device more accessible without compromising on quality.
