PULSAR-23 RUST: next-generation organismic drum machine

Designed by Vlad Kreimer, PULSAR-23 is a semi-modular analog drum machine that redefines rhythm synthesis. With 23 independent modules and an organismic architecture, it is designed to generate not only percussive patterns, but also basses, melodic lines, soundscapes and novel effects.

Simultaneous MIDI, CV and stand-alone control

PULSAR-23 offers a unique hybrid workflow: you can use it stand-alone, via MIDI or with CV-even simultaneously. In addition, you can harness the human body as a conductor for patching and live "circuit bending" modulations.

Advanced modules for unlimited creativity

Independent drums and loops

4 dedicated channels (kick drum, snare drum, hi-hat, percussion) with sustain envelopes that turn them into drone/noise generators. Each channel has its own individual loop recorder with optional quantization.

Clock, Shaos and FX under CV control

Clock generator with divider array, variable LFO 0.1-5000Hz, and Shaos: pseudo-random generator with 4 independent outputs. FX DSP with sample rate control via CV, plus analog distortion, VCAs, inverters and attenuators.

Extended connections and modular integration

With over 100 ports between inputs and outputs, PULSAR-23 is ideal for integration into Eurorack setups. It includes assignable attenuators, dynamic CV sensors and supports both mini-jack and 1/4" jacks.

Included in the package

PULSAR-23 comes in a handcrafted bag with power supply, 30 clip-on cables of different lengths and colors.

⚠️ Note: Since this is an experimental analog synth, it may exhibit slight bleed or noise in some contexts. It is not suitable for those seeking total isolation between modules.
