• 16 Waveforms selectable in two Banks of 8
• Frequency range: 0.05Hz to 12.8Hz (102.4Hz with multiplier x8)
• 6 CV inputs for Multiplier, Frequency, Step Rate, Skew, Waveform and Level
• "Sync" Input for LFO reset, or Step Sync
• 3 outputs:
Uni-Polar (0 to +5V),
Bi-Polar inverted (+5V to 5V / 10Vpp) and
Bi-Polar normal ( 5V to +5V / 10Vpp)"

Create Generative randomized Patch (Krell Patch) - CubuSynth

"Different ways to use random triggers and voltages with the CubuSynth modules which result in unexpected results and very interesting sounds.
This patch is fully stereo and is using the CubuSynth Engine (Dual VCO), the Dual CS-20 VCF and the Dual Vintage VCA.

CubuSynth - Dual CS 20 VCF - Sound Demo

video upload by CubuSynth Modular

"Dual / Stereo Multimode VCF with Self-oscillating Resonance and intuitive Routing and CV modulation Matrix

The CubuSynth Dual CS-20 VCF is a dual / stereo multimode VCF / Phaser / VCO, inspired by the legendary Korg MS-20, with CV control over frequency and resonance. The resonance can self-oscillate and features a 1V/Oct input, stable over at least 2~3 octaves.
Each of the two filter cores has 2 stages of Low Pass and High Pass filtering, which can be blended. The Frequency CV can be “attenuverted” (with inverting attenuator on CV input). The resonance CV comes with an attenuator."

- CV control over Frequency and Resonance for each Filter core
- self-oscillating Resonance with LED feedback circuit (visible on the Front)
- 1 V/oct input, tracking over 2~3 octaves
- Frequency Range: 22 Hz – 20 kHz
- Blend between LP / HP Filter modes
- Ability to use as 2 pole (12db) stereo HP/LP Filter, 4 pole (24db) mono LP/HP or a Band Pass (12db) Filter
- Cross FM Modulation possible

CubuSynth - 4VCLFO Demo

video upload by CubuSynth Modular

"The 4VCLFO is four LFOs with triangle Outputs in 10hp. It features a knob for the Frequency of each LFO and CV inputs with attenuators.

The 'Aux' input is normalized to the four CV inputs, so you can modulate all LFOs with one signal at the same time. Plugging a cable into the CV input breaks its connection from the aux input.
This way you can create more interesting Modulations for your Patches.

- Modulation routing in this video:
LFO 1 modulates Filter Cutoff frequency
LFO 2 modulates VCO wavefolding
LFO 3 modulates Pitch of VCO (01:00-01:20) and Aux CV (from 1:50)
LFO 4 modulates Release/Decay Time of ADSR"

"CubuSynth Engine

Complex analog dual VCO
Designed to bring a complex VCO, with a huge amount of possibilities and internal modulations to the DIY world, this module stands out for its visual appearence as well as its audible quality and possibilities

How it works
The CubuSynth Engine can work as 2 independent VCOs, or as a complex FM oscillator with its several modulated outputs.

With its inernal 'Chaos Engine' it creates semi-random voltages, generated by the 2 oscillator cores. This signal is then normalized to the CV inputs for Pulse width modulation and exponential FM.

Each of the 2 VCOs offers a switch to select one of the 4 waveshapes to be used by the wavefolders, and the linear FM input normalisations.
