New ADDAC 511 Stochastic Voltage Generator

Chance music: from dice to Addac's Stochastic Voltage Generator

video upload by Electrum Modular

"Addac sent me over their latest module: the Stochastic Voltage Generator. It inspired me to delve into the eccentric history of stochastic (or aleatory or chance) music, from Mozart to Marcel Duchamp, John Cage, Morton Feldman, and Iannis Xenakis -- and from Buchla, Moog, and Arp to Eurorack.

The accompanying patch is inspired by Feldman's graphic scores (especially the early "Projections" scores). David Cline's detailed book, The Graph Music of Morton Feldman (Cambridge University Press, 2016), was crucial to understanding Feldman's scores and his complicated relationship to indeterminacy."

"At ADDAC System we love all sources of unpredictability be it by randomness or signal complexity. This module greatly expands on the principles of our ADDAC501 Complex Random from 2013.

This is a fully fledged 4 channel voltage generator capable of all things random, with quantization, probability, distribution, interpolation, time control, clock, states and a 32 step sequencer.

The module panel features a screen for parameter editing, and each button offers access to a single page of changeable parameters. This allows for a fast and fluid workflow across all settings so users can focus on their music. The combination of two encoders along with push buttons allow swift navigation and editing across all pages and their respective settings.

FEATURES

4 independent channels with bipolar CV / Gate outputs and Clock Input that allow all things random.

Each channel can be set to generate either continuous Voltages, Envelopes or as a Quantizer.

Controls over Voltage Range, Quantization with custom scales, Probability, Distribution curves and Smoothing, plus time and bpm ranges, time distribution curves and several clock sources.

A 32 step sequencer per channel that can work completely independent or in sync.

Mutes and Holds per channel.

3 States per channel allow very fast settings changes, from smooth to drastic transitions.

8 Assignable CV inputs and 4 Gate inputs can be internally mapped to any setting of any channel.

3 configurable Logic / clock outputs allows complex logic events comparing different ins & outs or as clock outputs.

Average CV output of all 4 CV outputs. Easy VCO tuning available in the Menu.

Calibration and mapping of all 4 CV outputs is also allowed through the Menu"

DIY SYNTHS DATABASE



This one is in via the site's creator, Misha who had the following to say:

"I’ve curated a collection of 61 DIY-friendly hardware synthesizers and related standalone musical equipment. All open source.

I created this site to compile dozens of open-source designs into kind a database, making it easier for anyone looking to build their first synthesizer to choose a suitable project without additional research.:

And via the site's About Page:

"Hey, I’m Misha 👋. I have quite a bit of experience building open-source synthesizers based on schematics found in the depths of the internet. I created this site to compile dozens of open-source designs into kind a database, making it easier for anyone looking to build their first synthesizer to choose a suitable project without additional research.

The list is constantly expanding with projects that I curate. If a project is listed on the site, it doesn’t necessarily mean I’ve built it (though I’ve assembled more than two dozen of them), but it does mean I’ve verified that all the necessary build files are available, published by their authors, and accessible to everyone.

The minimum criteria for adding to the database are:

The project must have published schematics.
If it’s a digital device with a microcontroller, a firmware source code must also be available.
Video demonstration.
Not all projects in the database are synthesizers: there are also arpeggiators, sequencers, MIDI controllers, and more. Almost all devices are standalone units, meaning they have their own power supply and don’t require external control voltage to function."

The Twins Love System ~ PPG Wave System

One of my favorite tracks from the early 80s.
Love System by The Twins from the album A Wild Romance (1983)

Featured the PPG Wave 2.2 Synthesizer and the Waveterm A for sampling and wave synthesis. All sounds from the PPG System, including drums.

This cover song series contains my own recreations of my favourite songs from the last 50 years. The original music from which I take inspiration belong to their respective owners. I recreate tracks only for personal passion and to pay homage to these tracks.

My intention is not to create covers that sound exactly like the original (if you want to hear identical sounds, please listen the original). It's more of an inspiration with my sounds from the old synthesizers from the past and of course the great appreciation for the original performers and producers."

Spectral Audio Neptune 2 - Analog Rackmount Monosynth SN 50174

via this Reverb listing

"The Neptune 2 is a Swiss-made, all-analog mono-synth with built-in MIDI and CV/Gate in a 2-space rack-mount module. It features three true analog oscillators for a very fat sound. It has a 24 dB filter, but it is not as creamy as a Minimoog. All parameters and controls are available from the knobs and switches on the front panel in an intuitive and clearly labeled layout - bringing old-school analog synthesis to the modern MIDI studio.

These don’t appear very often. Not many were produced.

Look closely at the front panel in the photos. There are many features that don't appear on most monosynths. Most important: two ADSR envelopes, with modulation positive or negative for the filter. The filter offers Low Pass and High Pass modes. Oscillator 3 is a bass oscillator, or it functions as an LFO, with several waveforms and mod destinations (Targets). There is also MIDI control of filter and aftertouch modes."

1972 Moog MuSonics Sonic V Super Rare Synth #96/100 Made

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


via this Reverb listing

You can find a video covering the Sonic V previously posted here.

"Super-rare Moog MuSonics Sonic V synthesizer from 1972! This is #96 out of only 100 made and the only one I’ve seen with a front panel overlay that differs slightly than others I’ve seen (which, admittedly, is not many and not at all in-person). It’s actually more in the aesthetic style of a VI, as far as that particular detail is concerned.

The elusive predecessor to the Sonic VI was designed by Gene Zumchak, who also designed the 960 Sequencer, 961, and 962 modules. According to advertising literature, it was “designed for the music educator” and features “ring modulation, microtonal keyboard scaling, two-note keyboard capability, and extended modulation resources”.

The sounds this thing can make are absolutely insane. For those of you who are in to noise, sound effects, and sound design — this is a formidable and wildly entertaining beast. It is capable of some really beautiful, melodic sounds, as well, so it’s not just for pure craziness. It’s a unique instrument not often seen out in the wild and only in the collection of distinguished collectors, studios, and synth aficionados. A rare chance to grab an incredibly rare instrument!

Just serviced with the following:

- PSU recap
- all pots cleaned and a few jacks replaced
- ground hum eliminated
- 741 op-amp replaced in Oscillator A
- full calibration"

EML 200 and 300 Blue Face

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


via this Reverb listing

"Not something you see everyday! EML Electrocomp 200 with 300 controller.

These predate the more popular Electrocomp 101, starting the run in 1969. The blue faced ones were all made for universities, so I’ve been told. I don’t know a whole lot about the lineage here, but suffice to say these are extremely rare. The last complete sale I can find on Reverb was 6 years ago.

The units show pretty typical wear for instruments made nearly 60 years ago, but they’re in remarkably good condition. Everything works! A couple of the triggers on the 300 double trigger when tapped, and I would imagine the whole thing would benefit greatly from a cleaning.

Like I said, these are incredibly rare. So it’s difficult to even put a value on it."
