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."

"Building and Calibrating this wonderful Chaotic dual complex VCO by Cubusynth!

Suggested Mods:
R189, R190: change to 47K for higher Gain of wavefolder
R236, R237: adjust for offset of wavefolder (47k to 470k)
R2, R3: change from 100k to 110k for offset of Triangle output, also improves sine roundness.
R85, R92: change from 100k to 68k/47k for better sine roundness. Adjust R81, R96 for amplitudes. C20: replace with wire for a straight Pulse on VCO1.

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"

Chapters:
00:00 Filtermodes with Saw wave on Input
01:50 VCA on Input stage
02:45 CV (from LFO) on Cutoff Frequency
03:45 CV on Resonance
04:18 "Ringing" mode with Square LFO on Input
05:02 Quantized 1V/Oct on Freq CV + Melodic Jam
09:30 Stepped CV on Freq CV
11:10 Stepped CV on Input + Audio rate FM

The CubuSynth VCFA is a multimode VCF with LP,HP and BP modes with integrated VCA, CV control over Frequency, Resonance and Volume.

The CV input for the Frequency features 1V/Oct scaling over about 2~3 octaves. So you can even create plucky melodies
with the resonance in "ringing" mode.

The Gain control can reach a nice, soft saturation.

Key features

- 3 simultaneous outputs for Low Pass, Band Pass and High Pass
- Integrated VCA on input stage
- Input saturation on upper Gain levels
- CV control over Volume, Frequency and Resonance
- Frequency CV scalable for 1V/oct signals (stable up to 2-3 octaves)
- 'ringing' appears on upper Resonance levels

"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.
