The Eternal Now

video upload by davidryle

"American Format (5U) modular synthesizer performance in real time to a stereo track in Cubase.
For an atonal wash I used the Dove Audio Waveplane and WTF vco's through an Oakley Sound Systems Ring Modulator. I then sent it through A dotcom Q150 transistor ladder filter and a Lower West Side Studio Multimode Filter/Resonator and on to a fixed filter bank and a Frequency Central Stasis Leak digital delay. This drone wash comes in at the final section and ending.
The opening reed sound and accompanying organ sounds were derived from the Synthetic Sound Labs/Mutable Instruments (Braids) Woven Spirits module.
The initial reed sound is from the AUX output of the Woven Spirits through an SSL/Ian Fritz 5 Pulser and Oakley Sound Systems State Variable Filter. The filter is stepped with a random S&H from JNP Electronics.
The secondary organ chord sound is the Main direct output of the Woven Spirits in Chord mode. The combination of both elements are sent to an Electro-Harmonix Grand Canyon in DMM mode. Feedback is applied as needed for the drone sustain throughout the piece.
The bass line comes in next with a pair of STG Soundlabs Oscillators through a Dove Audio D502 Multimode filter in -24dB LP mode. The pitch voltage is from the upper Q960 step sequencer. It's timing is from a Catgirl Synth Master Divider, clocked from a custom Dual LFO/Analog Shift Register of Ken Stone (Catgirl Synth) design. An additional tap from the STG oscillator through a Corsynth C103 Frequency Divider/Multiplier module for a sub-octave feed.
The melodic line blended into the latter section is from a pair of Q106 dotcom vco's which are pitch controlled by the lower Q960 sequencer. Each vco pitch is from a separate row of the Q960. The Q960's shift timing is from the CGS Master Divider module. The output is routed through an Empress Reverb pedal in Blue Ghost mode. Panning is from the LWSS/Yusynth Panning Mixer.
All pitch quantitization is through a Moon Modular 565 series setup.
Additional voltage modulation to the Woven Spirits module are from the STG Soundlabs voltage mini stores, and vaious LFO's etc. Timing for the additional sequencers is also managed by the Moster Divider."

ASR Freez

Published on Jun 16, 2017 Robin Rimbaud-Scanner

"A little experiment using the Elby Designs CGS734 Analog Shift Register running three oscillators, the Verbos Electronics Complex Oscillator, Endorphin es Furthrrr Generator Oscillator and Harvestman Hertz Donut Oscillator, the latter of which runs through the 2hp Freez, triggered by a Modcon Quad LFO. Intellijel Metropolis is making the melodies. Meanwhile two separate melodies lines flutter and appear from Hex Inverter Orbitals, also clocked by Metropolis - using Make Noise STO and Intellijel Dixie 2. Add a little reverb and a terrible iPhone film and you have it :-D"

Psych tone emulation

Published on Mar 18, 2013 otherunicorn·40 videos

Don't miss the second video below.

"Please excuse the lousy camera work.
This patch emulates the old Popular Electronics "Psych Tone" project. I used a CGS13 Gated Comparator for the shift register and CGS39 Quad logic gate (XOR) instead of their odd NOR gate arrangement. Bits 5 and 6 were gated and fed back into the input of the CGS13. A floating patch cord to one of the EXORs was used to kick start it, and change the mode of operation from time to time. Tone selection switches were replaced with patch cords (non inverting pulses only) and mixed via a CGS81 processor (inverted or non-inverted) and fed as a CV to a Zeroscillator. At some point I add a 4th bit for added variety, and plug a sequenced oscillator into the Zeroscillator's polarity function."

Psych Tone - taking it further

Same description as above with "The modulating oscillator is being sequenced."

"Synthetic Sound Labs, Cat Girl Synth and Ian Fritz team up to make for a great sound. The Double Deka VCO designed by Ian Fritz and enhanced by Doug Slocum of SSL is a dual channel ultrasonic oscillator with loads of modulation parameters as well as ring modulation and cv octave switching. The CGS01 is a dual channel frequency divider, ring modulator, multiplier processor. When these two modules come together all mayhem is redefined.
The patch is both channel A and channel B from the DDVCO out into the CGS01 inputs. The outputs are then sent back into the DDVCO's Linear & Exponential FM inputs. The Lin FM is routed through a vca and modified by an SSL Tap Tempo LFO in places in the demo. Switching on the DDVCO is done on the Linear FM between AC/DC response.
A Tap Tempo LFO is also used in this demo to add some modulation to the Linear frequency FM input.
Various timbre are heard from the combo such as video game sounds as well as big bass, electronic percussion and formant sounds. I even had fun playing the sub oscillator like a motorbike throttle. No filters are used, but I did employ a Lexicon MX200 digital delay for some rhythmic fun."

Ghost Rider Modular

YouTube Uploaded by FOCtv on Nov 16, 2011

"Mr. Hand demos a patch utilizing a CatGirl Synth Sub Octave Divider module. The sequence is a facsimile of Suicide's song Ghost Rider done with a Q119 Sequential Controller. It's not the complete riff since Marty Rev's riff is poly-rhythmic and I could only use 8 steps of the analog sequencer. The organ-like tonality is from the CGS Sub-Octave module which can function similarly to the divide down technology used in electric organs."

Catgirl Synth CGS37 CV Cluster

via this auction

"Assembled by Free State Custom Electronics

Here is a breif description of how this module works from Ken Stone's incredible Catgirl Synth Website:

"The CV cluster is an unusual kind of mixer. It takes two input voltages - a base control voltage, and a modulating control voltage, and creates the sum and differences of them. These different voltages are the base voltage offset in a positive direction by the modulating voltage and the base voltage offset in a negative direction by the modulating voltage. A series of equal taps between these two points results in outputs that always maintain the base control voltage at its full amplitude, mixed with a differing amount of the modulating voltage. The center output has equal amounts of positive and negative modulation canceling each other out, and thus behaves as a
straight-through connection for the base input.

Some ideas on how to use this module:

Feed your 1/v octave input into the base input, and an envelope generator, LFO, sequencer etc. into the modulation input. Connect the outputs, starting with the center unmodulated output, and working both up and down, to a series of VCOs. While the modulation input remains at zero, all of the VCOs will track. As the modulation voltage increases, the VCOs connected to modulated outputs will shift in frequency away from the base, at an amount proportional to its position from the center output. For example, a small modulation voltage will de-tune the oscillators slightly, fattening the sound. A modulation CV of 5 volts will set each output 1 volt apart, setting the oscillators an octave apart.

An envelope generator connected to the modulation input creates in interesting effect.

It of course can be used with audio frequency signals too, and may prove interesting when driving a cluster of wave multipliers or similar. Two audio signals fed to it could produce interesting stereo effects.

Note: The sum and differences produced by this module are voltage differences, NOT frequency differences. It is NOT a ring modulator."

via where you will find more info and other people's designs of this DIY sequencer by Ken Stone's Catgirl Synth.

"An 8-step analogue sequencer/programmer, newly-built, not quite working 100% as yet. It's an iteration of Ken Stone's excellent design, and a set of PCBs is available here, if you want to build one yourself. Recommended, but not for a first electro-music DIY project, there's a lot of wiring up involved."
