Essential Information About the Eurorack Semi-Modular Analog Synthesizer
- Massive Analog Grain thanks to two VCOs, a 24 dB ladder VCF, and a fully analog VCA.
- Ready to Play: semi-modular architecture with no mandatory patching, but 48 connection points for further exploration.
- Immediate Creativity with a step sequencer, hold arpeggiator, and built-in memory.
- Full Integration in Eurorack format, Poly Chain up to 16 voices, and complete MIDI implementation.
A Semi-Modular Inspired by the Great Classics
This synth follows the lineage of historic modular systems, with a faithful recreation of the legendary "Model 15" circuits. It captures the thick sonic character and musicality of the ladder filter while adapting it for modern use: Eurorack format, MIDI control, and integrated performance features. It positions itself as an ideal bridge between the modular world and the workflow of stage or studio synths.
For Producers, Performers, and Sound Designers
Versatile and intuitive, it suits both beginners curious about exploring subtractive synthesis and experienced users seeking an expressive analog engine. Techno basses, synthwave leads, ambient pads, acid sequences, or cinematic textures: its palette covers studio, live, and sound experimentation, with immediate usability and evolving patching depth.
Features and Innovations
At its core, two VCOs deliver four waveforms, oscillator sync, precise pulse width modulation, and a sub-oscillator to reinforce fundamentals. The 24 dB ladder filter with resonance delivers an iconic timbre, from smoothness to self-oscillation. The step sequencer offers three memory slots of 256 steps each, instant transposition, and multiple playback modes, complemented by a "Hold" function arpeggiator. A fully analog LFO (four waveforms) has dedicated destinations for pitch, filter, and PWM. The spring reverb emulation adds vintage depth. With 48 patch points, 37 front panel controls, and Poly Chain up to 16 voices, this semi-modular integrates seamlessly into both Eurorack systems and modern MIDI setups.
