Expander for the PULSAR-23 Drum Machine


Expander for the PULSAR-23 Drum Machine

UTILITIES contains a set of simple auxiliary modules to expand the functionality of the PULSAR-23 drum machine. UTILITIES modules can also be used with any gear that works with CV signals (Eurorack, semi-modular synthesizers, etc.).

The modules included in UTILITIES can be divided into two groups:

1) Passive elements such as switches, resistors, capacitors.
2) Various types of amplifiers and waveshapers, linear, non-linear, controlled and uncontrolled.

Passive elements are designed to expand the possibilities of switching and controlling the PULSAR.

Linear amplifiers are needed when you need to feed a signal from a device operating in a lower voltage format to the PULSAR inputs. For example, it can be a step sequencer with an output voltage of 5 volts, while the PULSAR needs 10 volts to fully trigger the drum modules. Or it could be the output of a cassette tape recorder, which has an output of 1 volt, while for normal operation the PULSAR needs an input level of an audio signal of 5 volts. Non-linear and controlled amplifiers and waveshapers are designed to control the signal level, while simultaneously changing its spectrum, distorting its shape and adding harmonics. The circuitry of these amplifiers is very simple and based on the early developments of the transistor era, with its inherent beauty and grace.

UTILITIES' connectors are made in the PULSAR-23 format on pins designed to connect the alligator clips. There are also adapters for 3.5mm Eurorack mini-jacks. The top panel and enclosure of UTILITIES are made of PCBs.



You can visualize any PULSAR CVs by connecting these CVs to the LEDs input pins.


4 independent attenuators that allow you to adjust the signal levels by attenuating them. For example, this is necessary to control the depth of modulation of the filter frequency by the LFO output signal.


2 independent photoresistors that allow you to control signals using light. For example, you can include a photoresistor in the break of some modulation circuit and control the modulation depth by bringing your hand to the photoresistor.


Allows more convenient and masterful use of PULSAR's unique ability to be controlled by connections of various inputs and outputs through the artist's body. Connect all the necessary inputs and outputs to these contacts and manage them conveniently.


Just 4 reliable, easy-to-use buttons that can commutate any signal and endure the passion of your performance.
