Shootout at the Boomstar Corral - Resonant Filter Comparison by Marc St. Regis

Published on Jan 9, 2014 StudioElectronics·14 videos

"What was it they used to say in the '70s at the end of the 'Streets of San Francisco' opening credits? ... WITH SPECIAL GUEST STAR DREW NEUMANN.

Yeah that was it... wait for him.

The SoundCloud copy reads: "A Tombstone quality Boomstar 5089, 4075, 3003 filter shoot out/comparison. No tricks: no compression/limiting or gain maximizing, EQ, or plugins, just those snappy Studio Electronics hardware envelopes doin' work.

Each of the three Boomstar low-pass resonant filter synths have been put through near identical paces----no mean feat without programmability: and why would you want that in this purist platform? Artifacts and curtains would be in and in front of the sound, slowing and coloring, demanding tribute.

Patch matching contrasting hardware analog synths is not an exact science (sometimes a switch is missed or a pot or two is not precisely placed--you were sure you took a photo of that da#$ patch!) and tangy tangents are often explored at the end of certain sequences, once all the comparison fences have been cleared, but great care was taken to duplicate the settings and live switch flipping, knob turning and flying of the master performance, which could start out on any of the B*s depending upon mood and blind chance----if there is such a thing; mood is as palpable as approaching deadline storms."

But this is no mere SC re-tread: surprises, extended/edited and fresh material awaits.

That should cover the primary speil...

Performed by Marc St. Regis, with the marvelous exception of Drew Neumann's sharing of his 'Big Drum' vision on "Jehan's Mental Martaize," on which the 'no compression/limiting or gain maximizing, EQ' prohibition was specially dispensated off corral and ranch.

"This VCO has a very unique sound and tracks nearly 2 octaves with a HZ/volt CV source, But be warned, it is not perfectly scaled and is not temperature stable. That's not a defect its just the way it is, If you want pussy trance anthem pads or want to play Mozart then don't buy this. It's definitely a raw meat kind of aural experience, chewy and tough.

The METASONIX TM-3 consists of two thyratron tube sawtooth oscillators, which are wired in parallel but may be offset with their individual front-panel tuning controls. Furthermore, soft sync is available, to force oscillator 2 to track with oscillator 1.

The waveform produced by the 2D21/5727 thyratrons is unique and distinctive--a very imperfect sawtooth. It's the kind of sound that screams "VINTAGE", because the only other instruments that produce it are vintage ones--the Mixtur-Trautonium, the Univox, and some 1950s electronic organs.

Furthermore, there is a suboctave circuit, which adds a square wave one octave below oscillator 2. It includes short pulses an octave above, for a distinctive sound. And you can mess with the STABILITY control to get unique effects--because the suboctave divider is made of two neon lamps, and NOT a transistor flip-flop. Except for the CV driver, the TM-3 is all tubes.

And unlike most other synthesizer VCOs, the TM-3 is so sensitive that it is easily used for FM sound effects--simply by driving either CV input with a line-level audio signal. Both inputs are DC coupled and highly sensitive. The result is a unique, and very extreme, form of signal distortion.

The TM-3 is a Hz/V VCO, meaning it follows a linear characteristic. Each successive octave requires doubling the control voltage. As shipped, the first octave is swept from 0 volts to 0.25 volts, the next from 0.25 to 0.75 volts, etc. Although not standard to the present modular-synth industry, this scheme simplifies the TM-3's use as a signal processor, and avoids the use of an exponential converter circuit, which can drift with temperature or cause other problems. TM-3's CV control is compatible with vintage Korg MS series and Yamaha CS series synthesizers.

Technical specifications

Output signal max approx 10 v p-p. Capable of approximately 66 Hz to 526 Hz. Center pitch setting with tuning knobs and 0.0v input gives approx. low C (66 Hz). Actual range obtained depends upon individual thyratron tubes installed--about 2 1/2 octaves is typical. May be controlled from any MIDI-CV converter having Hz/V capability, including the Synhouse MIDIJACK II, Philip Rees Little MCV, Kenton Pro-Solo and Pro-2000, and Encore Expressionist.

Power input 10v AC to 12v AC, 50/60 Hz, 1 amp max at idle--derived from an appropriate plug-in AC adapter. Inputs: two 1/4" phone jacks for CV or audio (they mix linearly). Output: 1/4" phone jack, audio, mono, 50k ohm impedance.

Dimensions: 7 1/2" (192mm) x 4 3/8" (112mm) x 3" (77mm). Weight not including accessories approx. 5 pounds (2.2 kg).

This is used electronic gear in great shape (low hours) from a smoke free home studio. I test it before it ships, but it is non returnable and there is no guarantee other than it will not arrive DOA. Rock On!!"

Doepfer A100 Custom Suitcase Analog Modular Synthesizer System

Published on Jan 6, 2014 MarkJenkinsMusic·30 videos

via this auction

"3 VCO, 5 LFO, VC Delay and Trautonium Ribbon Controller System

This is my incredible custom portable Doepfer A100 modular analog synthesiser system, probably the most powerful it's possible to build in such a compact unit.

Think of it as two separate synths - the top row like a MiniMoog with three oscillators, mixer, Lowpass Filter, Envelope and Modulation Oscillator, the bottom row more like an EMS Synthi VCS3 with four slow oscillators, white noise/random, sample & hold, portamento, a voltage controlled delay line, a custom modulation joystick and a touch sensitive ribbon controller.

The power of this system for electronic, ambient, techno, abstract and film music has to be heard to be believed. Here's my YouTube demo [above] of the actual system on sale, please watch it to the end for important information about the sale."
