System 55 - Sequencer as Waveshaper

video upload by O.Z. Hall

"This video looks at using a sequencer, running at audio rates, as a waveshaper. Some sequencers, like the MOOG 960 have a voltage controlled oscillator for a clock. A keyboard control voltage (or another sequencer) can be used to control the clock. Other sequencers require an external VCO to clock them with a reliable pitch control."

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."

Wavolver II demo

video upload by O.Z. Hall

Click here for additional Wavolver posts by O.Z. Hall.

"The Wavolver II is a waveshaper that includes both a wave (manual) folder and a pulse waveshaper (with vertical offset and pulse width modulation ). It also includes a second pulse wave. This Eurorack module is available from Elby Designs. The circuit was designed by Ian Fritz.

I'm modulating is with a quantizer which is acting as a kind of sample and hold circuit."

Apex 9


"Live recording of the modular. The challenge was to create three distinct parts to string together to make a musical journey.

The first section is centered on the Moog Subharmonicon and a few extraneous sequences controlled by a Q119 step sequencer. The 24 bars passes through 3 segments with pitch transpose and discrete pad sounds.

The second section is isolated to a Mutable Instruments Rings and Delptronics drum patch with an STG PostLawsuit LPF with an Ian Fritz DDVCO swell.

The final third segment is two STG Soundlabs voltage sequencers with four vco's sourcing pitch voltages from a David Dixon ASR and run through a digital delay.

All these parts are managed by a sequential switch ( Q962) and a Q960 step sequencer.
Other sequencers included the MI Marbles, INSTRUo harmonaig, Make Noise Pressure Points (x2), and Moon Modular 563 Trigger sequencer.

I just stood back and started the thing and then tweaked some levels. Pretty easy money for managing the robots and all..."

Cave Giants


"A live performance with the 5U large format modular synthesizer.

Starting with an Encore Electronics frequency shifter and Yusynth Arp 4072 filter. Modulations to the frequency shifter from a Sputnik WCRS, and an Ian Fritz DDVCO in harmonic sequence mode.

The bass sequence is driven by the STG Soundlabs suite with two VMS and one TMS, a pair of EG's, a Switch module and the Time Divider. Clock timing from Cubase via dinsync to the Time Buffer. Four Q106's into a Q150 transistor ladder filter and an Oakley SVF.

The melodic sequence is a pair of Q960 sequencers to a pair of Q106's through an STG Sea Devils filter and Q107 SVF.

The percussive tick sound is a Sputnik voltage controlled slope.

Delays and reverbs include Behringer DD400's, Empress reverb, Strymon Blue Sky, Electro Harmonix Canyon, TipTop DSP with Valhalla Shimmer and Modcan 73B.'

Ian Fritz/Elby Designs ChaQuO Explained by Learning Modular

Learning Modular

"This movie takes a deep dive into how the ChaQuO – a quadrature oscillator driving a “double “well” second order chaos circuit – works under the hood. I deal with the design on both a building block and actual schematic level, meaning many of the concepts and explanations can also be applied to software emulations of chaotic modulators. What we learn in the circuit-level explanation is then applied to the controls on the actual module, driving just a single synth parameter – filter cutoff – to make it easy to hear as well as see the results."

Ian Fritz/Elby Designs ChaQuO 2/2: working in multiple dimensions

"Most chaos-based modules have multiple outputs, taken at different points in their internal feedback loops. All of the outputs run at the same underlying frequency and are related in a general way, but have different waveforms present. In this movie we exploring using it to drive two and then three parameters of a 2hp Vowel vocal synthesis module, making it 'speak in tongues'…"

STG LFO Sync Test

Published on Nov 15, 2019 davidryle

"Suit and Tie Guy Envelope Generator in LFO A mode. This thing loops in SYNC mode with the other sync bus modules to give a wonderfully musical performance tool for rhythm and phrasing.

I used an Ian Fritz DDUVCO and Synthetic Soundlabs VCO throughan Ian Fritz 5 Pulser for the sound sources. An STG Soundlabs Post Lawsuit Filter was used on the SSL vco and a Q150 ladder filter was used for the DDUVCO part.

A pair of Lexicon dual delays (MX200) added some tape delay DSP effects to the final signal.

The entire STG Soundlabs module suite can be bought from Check it out!"

"Another adventure with the Arturia MicrFreak, Empress Reverb and Strymon Blue Sky.
The opening sequences are from the MicroFreak. The bass is a pair of Q106 vco's through a Q107 filter. Sequenced by the Q119 step sequencer.
Clocking from the MicroFreak. Clock dividers included 4MS OCD and RCD.
Percussion by Korg Volca Drum.
I noodled around with the System 8 and faded out with a pair of vco's (Harvestman Piston Honda and Ian Fritz DDVCO) sequenced by MI Marbles. Digital delays provided by Modcan and Behringer.
Thanks for listening!"

Bass - PDO
Fuzzy tones etc - AFG (modulated by Bistromath)
Noise bursts - A-118
Bass drum - Orgone Accumulator
Snare drum - D-333

The Bistromath combines the Ian Fritz designed Threeler VCF, the ChaQuo and the Jerkster, and is an absolute beast.

EQD (short version)

Published on Sep 5, 2017 Richard Galbraith

"This is the second half of a video I posted a while back but then took down. I always liked the second part much more than the first part, so I decided to cut out the first 5+ minutes. Sorry for the abrupt beginning, but oh well. Here's the original description:

This was recorded in two overdubbed takes. The first take is a bed of deep synth tones, provided by my MU modular, with added Arturia Microbrute and Mutable Instruments Rings in Easter Egg mode.

The second take is a Sela cajon which I mic'd with two mics: one for cajon audio and the other plugged into the instrument interface in order to trigger Rings. Thus, in this take you can hear the strumming sound of Rings with every cajon hit.

Key modules include's oscillators, Q150 low pass filter, and quantizer bank; Megaohm Audio Delta low pass filter; SSL/Fritz Doubledeka oscillator; FSFX/Fritz Teezer oscillator, and the MOTM 480 band pass filter.

Reverb and effects by Valhalla DSP."
