Feedback Modules VCZIII EMS SYNTHI Based Voltage Controlled Oscillator Modules

VCZIII - Bass Sequence video upload by Feedback Modules

"VCZIIIA SAW is mixed with VCZIIIB SQUARE and with SUB modules.
All three are mixed to the VCF2600. The end of the patch is VCA2600 controlled by the ENV100.
You can hear the bubbly sound of the VCOs, these VCOs made with transistors are not so linear as other VCOs."

VCZIII - FM Modulation

video upload by Feedback Modules

"VCZIII VCOs modulating each other. The shape of the waveform is changed by the 4 slow sine LFOs combos of CMS SLOSINES. You can hear how the FM timbre is affected by the waveform nature."

via https://feedback-modules.myshopify.com

"The VCZIII voltage controlled oscillator modules are our latest creation and are based on the VCOs of one of the most revered analog instruments, the famous British pin matrix synth released in 1969. The VCZIII series VCO is a result of the collaboration of Feedback modules and CMS-LAB and is a modern re-creation of those temperamental, organic and beautiful sounding VCOs from 1969 but with enhancements and adaptations to the Eurorack needs of 21st century.

There are two type of VCOs, VCZIII A based on VCO1 with variable shape SINE & SAW waveforms, VCZIII B based on VCO2 & VCO3 with variable TRIANGLE & PULSE waveforms. Also, each VCO comes in two versions, one with normal fine tune potentiometers and one with precision multiturn potentiometer."

DUNE-Inspired Suspense-Style composition (Discrete Synthesizers CMS MR-15 Modular Synth & Eurorack)

video upload by Piotr Garbaczonek

"Thanks for watching!
After watching Dune for the second time last week, I wanted to make a new Dune-inspired composition. The scene I am specifically talking about is when Paul and his mother are walking through the desert, trying to find the Fremen, and they almost get eaten by a sandworm. I used the CMS synth for the dynamic arpeggio pattern and the eurorack for every other element. Everything is also going through multiple instances of Valhalla Shimmer in Ableton.

EXTREMELY RARE!!! C.M.S. MR-15 ModRack Modular System at Berklee (Copy of an ARP-2500)

video upload by Piotr Garbaczonek

"Thanks for watching!

EXTREMELY RARE!!! C.M.S. MR-15 ModRack Modular System at Berklee (Piece showing its possibilities) Every sound in this piece was recorded using the C.M.S. MR-15 ModRack Modular System, including drums and bass. It is not a performance, I recorded individual layers using different patches and only recorded one layer performed. All the other videos you see are of different patches as well as angles of this beautiful synth for your viewing pleasure.

If you want to find out more about the maker of the synth as well as his company, I will have both listed below. Phil's instruments are crafted with utmost precision, and it was so much fun to be able to use it for a few hours.

Vintage ARP Odyssey 1972 Mk. I + Full Patch Points + Cirocco Mods!

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Arp Odyssey Mk. I 1972, full patch points + Cirocco (C.M.S.) mods

Mods too many to list, but include (highlights):
Full patch points -- all main section outputs and all slider inputs
"Turbo" envelope switch, for true snappy (2600 style) envelopes
LFO free run
Back panel CV/gate controls
External audio input
A full set of mods can be seen from the picture. Mods were performed by #1 worldwide Arp tech Phil Cirocco (the guy who fixes/restores 2500's).

I should mention that another design quirk of the original Odyssey -- the delay between VCA and VCF gate times, has been eliminated!

Without this critical fix, no matter how fast the envelope times, it would have sounded slow due to the VCF gate delay. Not so here, the envelope is ultra-fast with the "Turbo" setting, and also sounds better and cleaner with the normal setting. This is what is meant by "true 2600 style envelopes" -- multiple coordinated modifications here really take this synth into a completely different category.

What you get is the 'best of both worlds'. You get additional features and sound of the early 1970's Mk. I Odyssey (much warmer early 1970’s oscillators, sweet filter resonance, hard sync), with the back-end snappiness and sonic character of the Arp 2600. On many patches the result actually sounds better than the stock 2600."

CMS 2500 Euro Rack Module Demo - 12 module system

Published on Mar 16, 2020 Phil Cirocco

"Here is a quick demo of the newly released CMS Euro Rack 2500 modules. This is my personal 12 module system. The audio quality and noise levels are actually superior to the original ARP 2500 system due to better layout of the circuit boards and no matrix switches. The flagship module of the series is the 1047 Colin Multi-mode Filter. Go to discretesynthesizers.com for more info."

CMS 2607 Demo - Beat Patch

Uploaded on Dec 31, 2016 precarious333

Similar to this 2600 piece. The video above is from 2016. You can find CMS 2607 posts including recent demos from CMS / Phil Cirroco here.

"Patch is 2607 only. No external input or CV.
-----------
Kick is the filter self-oscillating with VCO 3 saw wave modulated by the ADSR mixed in.

Snare/HH thing is noise through the Ring Mod in VCA mode.
ADSR is triggering both sounds, which are fed into the two inputs of the switch with the main clock switching between them. Both are playing every beat but because of the switch you only hear every other hit.

Base is VCO 1 saw wave modulated by the same ADSR, so falling on both the up and down beat. Patched through the lag processor (fourth horizontal slider) which works as a low pass filter on audio.

Tinkly sound is VCO 3 sine wave frequency modulated by VCO 1 with Sample/Hold supplying random pitched notes. Then run through processor two (third horizontal slider) which I manually switch between normal and the Post Filter Distortion circuit from the ARP Centaur.

Processor section one (top 2 horizontal sliders) is being used to mix the base and tinkly sounds to send to the VCA section where both envelopes work to shape the volume through both linear and exponential inputs.

Output of switch and VCA routed to the final mix stage with spring reverb into the unity gain input. This works great since reverb has it's own gain control at source.

Recorded as a mono track into Ableton Live 8. Compression used to keep things in check."

CMS 2607 demo - Sync, PFD and high-pass filter

"Phil Cirocco demonstrating the CMS 2607 just before shipping it out to a customer in San Francisco. The patch breifly highlights the built in sync circuit. Later in the video, the High-pass filter output is fed through the Post Filter Distortion circuit (from the ARP Centaur). The two 1/4 inch cables at top right are plugged directly into the stereo input of the camera. No post production or processing. The reverb you hear is the internal spring unit. discretesynthesizers.com"

Synth Spotting with Pete Townshend of The Who

via Pete Townshend's Instagram @yaggerdang

Cameron Jones, mentioned below, is the co-creator of the Synclavier. Curious about that new mac-based program. Cameron recently worked on the Synclavier iOS app and the Synclavier KNOB.

"Between tours I spend a lot of my free time trying to improve my various studios. I have a number of spaces (only one large studio big enough for bands) and each one has a different focus. Recently, after getting inspired by the Eurorack world, and by being able to carry small devices on the road - like Akai MPC Mini, Volcas and Digitakts etc - I realised I’d neglected my larger modular synths that I am damned lucky to have and even luckier to know how to operate. So here’s where I left things with my ARP2500 (restored by the wonderful Phil Cirocco of CMS) and MOOG 35 before I sadly packed my leaving trunk to go on the road. Two months!!! Spiders will move in. The sharp eyed among you might spot the controller and keyboard for my Synclavier 9600 and Direct to Disk system. This has also recently been revived because Cameron Jones created a new Mac-based computer program to run the old towers. Steve Hill’s installed it for me. Cameron also worked with Arturia to create the Synclavier V. This is a fine development of the old FM system. The three stringed things on the wall are all by Collings. Love their boxes. .
