Dr. Wiener Presents: Serge Modular 101: Using the Smooth and Stepped Generator (SSG)


Dr. Wiener

"This a full explanation of the Serge Modular SSG in the Eurorack Format from Random*Source. Here is a text description below from their site:

SERGE SMOOTH & STEPPED GENERATOR (SSG)
The Serge Smooth & Stepped Generator (SSG) is a complex multi-functional module which can be patch programmed to provide various slew and sample functions both for audio and CV signals. It is one of the essential Serge modules.

The Smooth section will place a positive and negative slew on input voltage transitions for lag effects, voltage controlled portamento and for low frequency filter applications.” In Cycle-mode (cycle jack patched to the input), the Smooth side “will oscillate yielding a voltage controlled triangle wave LFO. A high level into the HOLD input will enable the Smooth Function to be used as a track-and-hold circuit with voltage controlled slew rate.

The Stepped function can be used as a sample-and-hold with voltage controlled slew rate limiting. In Cycle mode, a pulse applied to the Sample input will generate complex staircase waveforms for control voltage applications and for use as audio signals.

The Coupler is an internal comparator which compares the output levels of the Smooth and the Stepped Generators. This output is useful for generating complex control voltages or random voltages.

The Random*Source version of the Smooth & Stepped Generator for Euro is a licensed and authorized adaption of the original Serge design that provides an increased audio range of the Smooth Generator and a bipolar (“hot”) Coupler output in addition to the regular (unipolar) Coupler output."

"All sounds (except drums) from Waldorf MicroWave. Programmed from an Atari TT running Cubase 3, for that authentic 80's feel!"

Sequence #8 // 0-Coast, Digitakt, Spitfire Audio BBC Symphony Orchestra


Stefano Mattia - Eon Edge

"I finally got around to setting up my 0-Coast with my newly acquired Digitakt, all synched up with Logic Pro via Overbridge. It took me a while to figure it out but everything is working amazingly now. I don't even need an external audio interface anymore, I can hook up my 0-Coast into the Digitakt input ports, and have the Digitakt act as an audio interface itself. All channels, including the external ones, are acquired and recorded independently in Logic via Overbridge.
As I first test, I wanted to make some sort of ambient techno, with some nice punchy drums and a little bit of orchestra in the background. As usual, I got carried away a bit. But I thought it might be useful to share my first attempt, hopefully someone more experienced than me will comment with some precious constructive feedback.
In the long run, I want to get better at programming drums and arranging tracks and I hope that the Digitakt will help me in that compartment.
Let me know what you think of it :)"

Reminds me of the KORG Poly-61.

You can find demos of the CADANS S-12 in previous posts here.

"Up for sale one of the rarest Soviet synth from the late USSR - CADANS S-12. The synth after full profesional service (recapped, tuned, cleaned). T he power section is modified for more stable working by advices of Cadans creator. Original Case + 5din to 1/4 TRS jack cable included!

Bonus: random vinyl with Soviet electronic music ;)

This synth was manufactured In USSR by Tula Musical Factory, it's a one of the first hybrid synth productions in the Soviet period. It are digital but has analog filter and chorus, 64 patches, tape interface, chord memory, 2 independent DCO's, extended envelopes and other parameters.

Cadans has a warm old school synth sound, also can be used for modern timbres, the built-in quality design and unique powerful functions give you a big potential for your ideas and sound creations! It plays better than Poly-800 or Alfa Juno!

"The Oberheim OBMx is a modern synthesizer module with an audio path that is entirely analog. It has an intuitive and powerful interface which makes it easy for anyone to program their own unique sounds. The OBMx delivers the classic Oberheim and Minimoog sounds while being completely programmable and midi compatible.

An historical point is that the OB-Mx is, at present, the last synthesizer designed by Don Buchla. The 'Oberheim filter' provides 12 dB/oct low, band or hi pass filtering, with resonance. And the 'Minimoog filter' uses a 24 dB/oct low-pass filter.

The OB-Mx was one of the few real analog synths, available with completely modern features. And because it comes from Oberheim, you can expect great sounds, design, and features. The OB-Mx is highly user upgradeable. Out of the box the OB-Mx comes with one two voice expansion card which contains the two oscillators, 4 multistage envelopes, 3 LFO's, and filters. Up to 6 of these cards can be easily installed sufficiently adding to the phatness of this synth and its capabilities. It has been used by Nine Inch Nails, Sneaker Pimps, Apollo 440, DJ Spinna, and U2.

Along the bottom of the front panel is a set of buttons marked VOICE STATUS - the LEDs in each of these buttons light up to indicate which voice is being played at a given time. As well as being quite useful, these offer the added benefit that anyone looking at the panel can at least see some action!

Each voice consists of:

- Two Voltage Controlled Oscillators - Two Voltage controlled filters
- A mixer module
- A Voltage Controlled Amplifier
- Four Envelope Generators Three Low Frequency Oscillators."

Moog Model 15 Legacy Modular System (USA/2015) SN 17

Only 150 were hand-made by Moog (North Carolina/USA) in 2015. This one is serial number 17; obviously one of the first shipped to the UK (dual-voltage 120/220V, so no convertors required). One owner from new, apart from Klassic Keys GB. Rig comes with everything shown in photos, including special output cable. Original owner's manual (which is very informative ) & some patch charts + many patch leads + Swan flight-rack, even the original box! Note certificate of authentication...

If you are reading this, you will probably know exactly what this modular system is capable of. Basically, it is a portable version of the monster Moog system 900, which was extensively employed to produce "Switched on Bach" circa 1968. ANY sound/tone can be created....from scratch....and there is NO better tonality in the whole universe than a Moog system.......There are ten or so different modules (eg 995, 923 etc) all grouped in one "frame"; by plugging and connecting with the patch leads, the sounds are created, stemming from twin oscillators (921B), controlled by the master oscillator (921A), and so on.....

Introduction (by Bob Moog):-" ...is a pro modular system, made with the same high quality, precisely-engineered components as the largest Moog studio synths. Its compactness and convenience make it ideal for live performance on location, yet it is expandable into a studio system of any size. It combines functional simplicity and logical layout with the versatility necessary for producing a full range of sounds & effects."

Musically, you will need a keyboard. Option (1) use a Moog model 951/952...it simply plugs into the rear of the unit, no grief....(2) use software + any contemporary CV/MIDI mini-synth/mother keyboard (there are many available).....(3) use an external sequencer (only), if you are into the massive "techno-house-music-modular-synthesis" stuff......
Condition:- virtually "as new". No more, no less.
