Knobula Monumatic
8-voice virtual analog polysynth with 16 oscillator modes
12 HP Eurorack module
Monumatic is an 8-voice polyphonic and monophonic virtual analog synthesizer in 12HP. It features 16 oscillator modes modeled entirely without samples — from Roland-style supersaws and Polymoog Vox Humana to Casio phase distortion, drawbar organs, and lo-fi tape strings. Six filter types (LP24, phase, vowel, low-pass SVF, notch, high-pass) with drive and key follow shape the sound, followed by a built-in stereo reverb. Every front-panel knob has a secondary Shift function, and two assignable CV inputs (CV A, CV B) can be mapped to any parameter by simply plugging in a cable and turning the target knob. Supports both CV/Gate (mono with polyphonic layering) and MIDI (8-voice poly with MPE), plus 8 programmable chord memories for instant chord playback from a single note.
