Rare Vintage Moog 981 Mixer Module from 1967

This one is in via Thesis Audio Service who had the following to say:

"I came across this very rare module in a 1968 Moog IIIp that we are restoring for a client. It is a model 981 four channel mixer which I can find very little info about. It appears in the classic Wendy Carlos modular picture and in some Max Brand pictures. There is no mention of it in any of my Moog archive literature or service documents. I have included the schematic that I derived from it. It is an AC coupled mixer for audio. All of the IIIp system pictures that you find show a multiple panel in it's location in the system. The IIIp that we have is dated 1968, but this module is dated 1967. It's a bit of a Moog unicorn, possibly built by the master's hands himself."

I believe this is the first Moog Model 981 module to be featured on the site. You can see the Model number designated as 981 in the image below. The serial number is 1002 and the date is NOV 10 1967. R.A. MOOG CO. TRUMANSBURG N.Y. is on the label. You can find a circuit diagram below as well.

Thesis Audio Service also sent in the rare Moog Model 903 White Sound Source posted here.

Modular Journey to Industrial Trance - Modular Synth Jam

Published on Oct 1, 2019 Corsynth

"I was having fun testing the DR-03 Hihats / Metal prototype and I decided to record it.
All sounds come from the 30 spaces Corsynth Modular. Everything was recorded in real time in 6 individual tracks. Only effects added are a bit of reverb and delay."

Novation Circuit - Gradient

Published on Oct 13, 2019 Silver Reef

"About a month ago, I bought an Arturia MicroFreak to add another synth track to my Circuit. The MicroFreak was fun to play around on, but I had a hard time making sounds that integrated well into my tracks. I ended up selling it, and went for something a little more unconventional: a cheap electric guitar off Craiglist! It doesn't get more analog than that :P

The only exposure I've ever had to guitar was a half-year class in junior high, so I hope I don't offend any guitarists with my awful playing. I think it sounds really nice with the Circuit, though! Nobody cares about your technique when you drown your playing in reverb and delay, right?

The Circuit is sending mono out to one input of my Scarlett 2i2. The guitar is sent to the other input, and processed with the HyBrit Amp Modelling VST by LePou, TAL Reverb 4, delay, and compression. The final track was then mastered with Ozone Elements 8."

Roland JU-06A demo

Published on Oct 13, 2019 Hunart©

"Hi everyone!

I`ve got my hands on the new JU-06A. Mainly I`ve concentrated on the Juno-60 emulation but of course the 106 side was used too.

Every sound (the drums too) comes from the JU-06A. Beside some low cut at 30Hz (heavy bass in some cases) and some limiting there`s no EQ, compression or external FX."


Published on Oct 13, 2019 LESINDES

"This is the first episode of PURE ANALOG -- a project to find out and show the qualities of analog synthesizers and eventually also hybrids. And exciting Question is also how contemporary synths like this lush GRP A-2 or EREBUS NYX compare to vintage legends like MINIMOOG or ARP ODYSSEY or ROLAND JUPITER 4 etc. So this piece will be played and performed with different synths in the future track by track recorded in DAW without any equing or otherwise processed in DAW, no add modulation, reverb, saturatio or other FX. Only a mastering compressor, EQ and Limiter is used on the sum. So what you hear is completely un-FX-ed material -- almost impossible to find these days!!!"

Ambient Performance with AJH Synth Precision Voltages & Wave Swarm

'Analog Ambient' Performance 1 - with AJH Synth Precision Voltages & Wave Swarm

Published on Oct 13, 2019 DreamsOfWires

"Using the new AJH Precision Voltages Eurorack module in a real-time performance/recording. Also using the Wave Swarm to create string and choir-like timbres. All sounds are purely analogue (all from the AJH Synth system), no samples, and only digital reverb is added. This composition is a work-in-progress for a future Bandcamp release/album, and I have shortened it for the purposes of this video. See 'About...' at the end of the description.

Turn on subtitles to see a step-by-step rundown of how I'm using these modules in the video - hover your mouse over the transport bar at the bottom of the video and click the square Subtitles icon.

The incredibly useful Precision Voltages module makes a lot of things possible in performances that I've wanted to do for some time, and you'll be seeing it in future videos too. I've also used the Wave Swarm which can take the sound of a single VCO and create some very dense, haunting timbres, sometimes reminiscent of choirs, strings, and particularly old string synths of the past.

Elektron Octatrack MkII Dynamic 8-Track Performance Sampler

via this auction

"Mint DPS-1 mkII: used on a couple of studio projects over the 18 months I've had it:

100% functioning and sounds great
OS 1.30c (latest but one)
nice printed manual
16GB CF card - plenty of samples included
original Elektron USB cable
original box (tape on outside) and packing etc.

The OT mark II is easier to operate than the original (I had a loan of a mkI for several months). It's a long road to master this incredibly deep box but starting out and getting really interesting results - not too hard.

8+GB of library sounds included. Adding more as I find them on my hard disks."

JMT DNVO-1 Desktop Synthesizer with pattern generator, 3 Sub-Oscillators, CV In

Published on Mar 29, 2016 JMT SYNTH

via this auction

Pic of the inside below.

"Up for sale is one of our three beloved DNVO-1s from JMT Synth. This is his flagship model and the most requested desktop synth in our studio. For fans of Skychord/ KingCapitolPunishment/ Soma, though nothing in the 'noise/drone synth' category can touch the versatility and musicality of JMT's top shelf designs. Additionally, while the Skychord and Trogotronics synths are amazing in their own right, they are made using PCBs. JMT synths are 100% hand made, hand-wired and discrete, with no two sounding alike. This particular box was built to order by designer Tetsuji Masuda, and purchased directly from JMT Japan as a backup when our others (including the one with the blue status light in the video below) were tied up making otherworldly sounds for season two of a particular N__f___ series we worked on. It has seen no real use outside of testing. 100% hand made, hand-wired and discrete. CV input (VCO), 3 sub-oscillators, noise generator, 3-range VCF that can be tuned to the input signal, proprietary oscillator, military-grade build spec, can run on 1 9V battery or standard center-negative 9v PSU. I own a number of JMTs and this was my third DNVO1. (We're also parting with two of our UNVO1s--click on "seller's other items" to check them out. They're in equally pristine condition.) Ships with full factory warranty, in OB with panel diagram.

Analogue Solutions Impulse Command

via this auction

"The Impulse Command is a very unique analog synth. Its got a stereo filter section, digital effects, and an interesting loop sequencer. This is a great box for generating musical ideas and inspiration. There is a full row of patch points for interfacing with other desktop synths and Eurorack systems, and of course MIDI interfacing. This synth is in great shape and includes the original box and power supply."

Meant to be mounted under an organ or piano as an accompaniment, you can hear the early sounds that would later be found in the CR78 and 808 machines.

"I look at the inside the unit and installing a replacement 16x1 backlit LCD display. Final job has wires neatly tie wrapped and insulated with shrink wrap.

Backup battery seemed fine, but swapped it out anyway as a precaution.

I used some autosol metal polish to clean up the LCD display cover and case.

TX7 Controls:

- wheel amount control
- aftertouch amount
- foot control amount
- breath control amount
- Midi channel assign
- mono or poly mode
- pitchbender range amount
- volume gain mix
- portamento amount
-DX7 COMBO MODE The TX7 is basically a polyphony expander for DX7 and many functions are accessible only using the original keyboard. The performance mode team-up with the dx7 and a special set of sounds is provided for both TX7 / DX7.

I`ve had a chance to try out the Roland MC-707 groovebox. I`ve had just 4 hours to learn the basics and record something so I`ve decided to record three basic examples using just the built in content. No external EQ, compression or FX, just some limiting on the whole material.
