Patch Your Own Sound With Our Eurorack Synthesizer Modules

VCF-X

The LeafAudio VCF-X is a 4-pole analog filter based on the original TubeOhm design. It combines the warm SMR4 character with the flexible 4PM concept, offering 15 selectable filter modes including lowpass, highpass, bandpass, notch and phaser-style responses. An LED matrix shows the selected mode.

VCO-1

VCO-1 is a analogue oscillator. It is temperature-stable and delivers clean 1V/oct tracking across a minimum of four octaves. The module provides saw and square wave outputs, with the square wave being modulatable via CV or the PWM potentiometer. This allows precise control over pulse width, adding movement and dynamic character to the voice.

EXP-1

EXP-1 is the expander module for the VCO-1. It adds an LFO (bi-polar LED) with two waveforms (square, triangle) and various modulation targets, like sync, linear FM, wave morphing, an additional and a triangle output. Together with VCO-1 it is a sophisticated oscillator with lots of internal or external modulation possibilities.

Noisefoc

Noisefoc is an experimental noise Oscillator. It gets its distinctive sound from three CMOS NAND gates which can be controlled by a potentiometer, CV and a light dependent resistor. Two mixing circuits (one with diodes and one with resistors) to mix the oscillators and a power starving function which makes the device completely out of control.

Passive Utilitys

ATT, MLT and FPF are little passive moduls which are designed to be flexible and easy. All of these modules are available in 1U, 12HP and 3U, 2HP
