List of modules at the listing and captured below.

"Large-format modular system offers: 40 modules of various brands and 150 Synthesizer.com modules. In addition, there are various power-related modules, mounted in the front and the rear.

The system is 275 MU’s front face panels spaces plus 32-more in the rear. Featuring: 27 full-range multi-waveform oscillators, 12-filters, 3 discrete MIDI interfaces, and 4 sequencers. ( not including the Matrixbrute features)

It has taken over a year to purchase and assemble all of the modules: this system is completely ready to use. Most of this system is housed in solid walnut cabinetry.

There are a few modules I bought in used condition, but the rest are new purchases. The cabinetry, controllers, and cabling are all new. After assembly, this system has not been moved, exposed to smoke, or touched by anyone but me.

The entire system is in excellent condition, with a couple of VERY minor scuffs where modules have been periodically installed and/or relocated...

History: I first purchased a Moog System-55 re-issue modular. I discovered Synthesizers.com when doing a simple google search. I learned their clone of the Moog Dual Sequencer Compliment wing was not only superior to that of the Moog’s, it was nearly 1/3 the price. So from there, I bought a System 66 and A/Bd both the tonal and functionality aspects of each to discover the Synthesizers.com sounded better to my ears, had more functions, and was more stable. I sold the Moog, and steadily expanded the system it is today.

I am 100% satisfied with this system.

It would take upwards of 6 months to get all of these modules (and a couple of these you may not able to get at all) and a significant amount of time to install and wire the modules, and assemble the large manual binder.

It also took 2 full days to convert 16 of the modules into their revised versions, yet I have not added the price of the conversion kits to the list below."

Folktek Mescaline - Mutable Instruments Elements + Edges - Reverbs, Delays & Instant Lo-Fi Junky

Published on Dec 21, 2017 isvisible isinvisible

"The Folktek 'Mescaline' is providing the percussion (everything apart from the quiet snare sound which is from Braids) and the low repeating lush reverbed sound.

The wonky continuous slightly phased sound is 'Edges' going through my 'Bistromath', a ZVex 'Instant Lo-Fi Junky', Mungo 'd0' and an SDS Digital 'Reflex Liveloop'.

The slightly orchestral-ish sound is a Mutable Instruments 'Elements' fed into a Tiptop 'ZDSP' and then fed back in on itself.

The struck bowl (more like clunky synth percussion to be honest) type sounds that come in towards the end are the Livewire 'Dalek Modulator' going through a Doepfer 'A-188-2' delay.

Some sequencing being done by a Polyend 'Seq' via the 'Poly' module, and some being done by a 'Turing Manchine' and a Doepfer 'A-155'.

Triggers and gates being provided by an ALM 'Pamela's Workout, Mutable Instruments 'Grids' and Iron Ether's 'Pithoprakta'.

Modulation being provided by Livewire 'Chaos Computer', Mutable Instruments 'Peaks', Ian Fritz 'Bistromath' and a few other things, along with some Doepfer envelopes."

Ganymede Terminal

Published on Feb 5, 2017 davidryle

"Space Music, YES. An imagined moon base on Ganymede off Jupiter.

Modular synth for the bass line, percussion and a 16th note octave sequence.

The Oberheim/Dave Smith OB6 for a starting arpeggio, the Roland System 8 for some bridge chords and the Behringer DeepMind 12 for reverb-drenched chorus chords.

The main bass line sequence and percussion were generated by STG Soundlabs Time Modules. The bass sounds realized on the Moslab 901 VCO's and 904-A LPF.

The sixteenth note line introduced halfway in is the synthesizers.com Q119 sequencer to an Ian Fritz/Doug Slocum Double Dekka Ultrasonic VCO fed to two EG's and a Yusynth Minimoog filter.

Delays included Modcan dual delay, Lexicon MX200 (x2) and Behringer DD400.

The snare is a TipTop Audio SD808.

Played live in the studio and recorded to a single stereo track in Cubase. Video recorded with an iPhone7 and edited in Final Cut Pro."

Modular Synth Live Jam, with live looping.

Published on Jan 26, 2017 LOOK MUM NO COMPUTER

"First live session of the year. using a vegetable Oil can to set the pace. and just a whole lot of modular. and pitched vocals.

Recording is on soundcloud :- https://soundcloud.com/lookmumnocompu...

Vegetable tin goes into a very dodgy looper I'm working on, more info to come. what you see is the extent of its functions though, and it only works in that tempo, for now. juno 106, has max release and is going into a VCA controlled by modular stuff, the sequence was pre programmed before i filmed, so it was a case of increasing the length half way through to open up the rest of the bass riff.

Lots of Arduino's involved. for sequencing modules, arduino nanos to be precise.
Drums are Hexinverter Électronique Mutant drums. except for the clap which is a sample on a SparkFun Electronics, Inc. Wav Trigger. VCO's are jurgen hailble's living VCO's, going into an ms20 style filter, schematic can be found by ian fritz. loads of other stuff..... testing out a panning module i made too which is more of just a switching module.

Yamaha CS10. Vocals going into a Roland vocal transformer then into a Boss Effects Pedals DS-1."

Cottontail

Published on Oct 30, 2016 davidryle

"Large format modular and Eurorack modular with a looping sequence from the Roland System 8.

The System 8 is sending cv and gate info to a Mutable Instruments Rings and Clouds to generate the very last 8th triplet bell sequence sound. That is doubled with the S8 patch in the modular and sent through a Modcan Dual Delay. The timing for the sequence comes from the Suit & Tie Guy Time Divider to the trigger input of the keyboard.

Everything else is clocked from a midi to dinsync signal into the Pamela's Workout divider. The 4MS Quad Clock Divider, Moon Modular Octal Clock Divider, Intellijel Plog and a Dotcom Q962 Sequential Switch are used to generate other timings.

The main bass line sequence is a Q960 in 5 step pattern, row switched through a Q962. The sounds are the Mos Lab 901 suite through a 904 filter and STG digital attenuators.

The secondary upper sequence is a pair of STG Soundlabs Voltage Mini Stores which again are row switched in a five step pattern through a Malekko switch module. The sound source is The Harvestman Piston Honda mk1 into a Music Thing Spring reverb and TipTop Z-DSP with Clocked Delays chip. AR timing is from an Intellijel Quadra+Expander to an MST Dual VCA.

Both of these sequence patterns are transposed with a dotcom Q119 sequencer. Timing for the change is from a Q173 Gate Maths.

Kick sound is a Sputnik VCS through an Oakley VC State Variable Filter and timing from a Moon Modular 562 Trigger Sequencer. Noise swashes are Sputnik WCRS through an Synthetic Sound Labs Segwencer IV into an STG mixer and on through a Jurgen Haible Tau Pipe Phaser. Additional filtering was through a dotcom Q150 and Q107.

The last sequence is from an Intellijel Metropolis to an Ian Fritz and SSL Double Deka Ultrasonic VCO. The VCO is sent through a MOTM 440 LPF and a SSL Steiner Filter (high pass) on through a dotcom EG and Behringer DD400 digital delay. It is then sent to a Strymon Blue Sky reverb in plate shimmer mode. The MOTM 440 filter is frequency modulated by a bank B output of the DDVCO through an Encore pitch shifter.

Recorded in Cubase in one pass. Video edited in Final Cut Pro. Text title made in Motion."

"My Ian Fritz panels (Serge) playing very nicely with my Eurorack set-up.

The AFG is clocking the Pithoprakta, which in turn is triggering everything else.
Elements - Bass
Rings - Processing audio from the Radio Music
AFG - low clicky audio processed by the ADDAC Fixed Filter Bank, which has each frequency being modulated by various Ian Fritz designed modules (Chaotica, ChaQuo and Jerkster)
Serge Modular (Ian Fritz - Chaos Theory and Timbre Tantrum panels) - Plinky plonky piano sounds, warbles and atmosphere.

This one make me think of what John Carpenter might sound like exploring modular. Very Carpenter-esque. Love it.

Borderlands

Published on Jul 9, 2016 davidryle

"I recall driving along Highway 9 in south New Mexico from El Paso, Texas to Animas, New Mexico on the way to Tucson, Arizona. The long bouncy road made an unforgettable impression of the remote southern US border region.

I tried to produce the drone impression of the road noise and wide open scenic expanse in this project.

A live studio take of the modular synthesizer recorded in Cubase and captured by the iPhone. Video edited in Final Cut Pro.

Some module patch highlights include the MI Clouds in Parasite Resonator mode dealing with a few voltage controlled radio station audio signals and one of the melodic sequencer lines.

The bass line is a Q960 step sequencer sent to a Q106 vco through a Yusynth Minimoog LPF. It is sent through a Modcan dual delay and Lexicon studio delay. There is a doubling with the MakeNoise Mysteron through a STG Sea Devils filter and the TipTop Z-DSP with Halls of Valhalla.

Other sequencer lines play various slow melodic passages over the top. Some of the vco sources are half dozen Q106's, Mos Lab 901 + 904A suite, Harvestman Piston Honda and Ian Fritz Synthetic Sound Labs DDVCO through Yusynth Arp 4072 LPF. Effects included Strymon Blue Sky reverb, Behringer DD400 delay, SSL 1310 digital delay, Lexicon MX200's and TC Electronics D-Two.

A periodic low frequency drum sound is generated by an envelope to a STG Post Lawsuit LPF and noise from a Sputnik WCRS.

Clock timing handled by Cubase to Future Retro Mobius which drove the STG Soundlabs sequencer suite, 4MS RCS and QCD and Moon Modular dividers, Pressure Points as well as the Q960 and Q119 sequencers"

Serge Modular Synth - Ian Fritz 'Chaos Theory' & 'Timbre Tantrum' Panels - #2

Published on Jul 9, 2016 isvisible / isinvisible

"Playing with the two Serge format modular synth panels by Ian Fritz, 'The Timbre Tantrum' on the left and the 'Chaos Theory' on the right.

The only other things used apart from the two panels were:
Doepfer A-156 - for quantizing the S&H outputs of the Dual TGTSH.

Bandive Accessit Stereo Spring Reverb - for adding spring reverb to one of the Teezer TZFM VCO's. (the plinky plonky piano one).

Roland DEP-3 - for adding reverb to one of the Teezer TZFM VCO's.

Ibanez AD-202 - for adding delay to bank A of the DoubleDeka Ultrasonic VCO.

Serge - Ian Fritz DoubleDeka as a Trigger Sequencer

Published on Jun 17, 2016 isvisible / isinvisible

"Here's a video of a two panel Serge system comprising of two Ian Fritz panels. A Timbre Tantrum and a Chaos Theory.
The DoubleDeka VCO is acting as a trigger sequencer. It's triggering the following:
Bank A:
1. One side of a dual TGTSH (fed by the Chaotica)
2. A Teezer TZVCO
3. 4X4 AD/AR
4. Threeler VCF
5. Mixer

Bank B:
1. One side of a dual TGTSH (fed by the Chaotica)
2. A Teezer TZVCO (this one needs calibrating)
3. 4X4 AD/AR
4. One side of a Dual 2Q/4Q Multiplier
5. Mixer

Both banks mixed together and fed through a Bandive Accessit stereo spring reverb.

The second TZVCO (Teezer) needs calibrating, so sounds a bit off higher up the scale.

Cheers"

Reznik Dreams at the 1AC

Published on Jun 13, 2016 davidryle

"A wandering dreamlike idea. Using the Flame Chord Machine, Piston Honda, Clouds, Mysteron and Segwencer IV (two of them) to follow the Pressure Points sequence and radio noise which is stepped from a Q960 sequencer. Lots of random treatments with two Turing Machines.

The voltage controlled radio module, a noise module, a MOTM 440, a Serge 1973 filter, a CGS Real Ring Modulator, an Ian Fritz DDVCO all worked with feedback loops through an Encore Frequency Shifter to create the metallic noise.
The Segwencer was picking apart the four part chords in random fashion from a Turing Machine and the arpeggiator portion of the Chord Machine drove a suite of MosLab 901 vco's to add counterpoint to the Piston Honda sequence. The Mysteron and a Q106 vco were filtered through a STG Soundlabs Post Lawsuit LPF for the bass line.
A little homage to a favorite 'machinist' movie."
