Morphor VCO – fully analog voltage-controlled oscillator for Eurorack systems, built around the 3340 architecture, in a 6HP format.
The module provides four independent waveform outputs - triangle, sine, square, and saw - available simultaneously, letting you blend several waveshapes from a single oscillator without adding a separate mixing stage. A three-position octave switch shifts the tuning range in steps, while a dedicated tune knob together with a CV input and an attenuated FM input give precise pitch control for both manual tuning and modulation from a sequencer or another oscillator. A hard sync input and pulse-width modulation (PWM) extend the module into synthesis techniques beyond basic waveforms.
A tonal foundation built on the classic 3340 chip
The 3340 architecture, known from many classic analog synthesizers, accounts for the characteristic tuning stability and warm timbre of the analog-generated waveforms, with no digital signal processing anywhere in the path. That foundation lets you build bass lines and lead sections with a classic analog character, while benefiting from a modern, miniaturized implementation of the chip inside a compact Eurorack module.A compact format without functional compromises
At just 6HP wide, the module packs four simultaneous waveform outputs, hard sync, PWM, and an attenuated FM input - a feature set typically found on oscillators with a much wider panel. That matters directly when building out a larger modular system, where case space is a limited resource, and every HP saved leaves room for another filter, envelope, or sequencer module without giving up full oscillator functionality.KEY FEATURES
