GEMINI 2412 User Guide Part 1: The Single Filter (Explaining the individual VCF with audio examples)

video upload by AJH Synth Official

"Part 1 of 3. The AJH Synth Gemini 2412 Dual Multi-mode SEM-based VCF explained. The 3-part User Guide will cover this very complex and fully-featured, yet simple to use analogue filter, starting with looking at one of the individual filters in isolation. There are also some audio examples, both with and without talking, and some example patches for just a single filter at the end.
Part 2 will explain the central mixing bus section of the filter, and Part 3 will cover using the both filters together with the mixing bus, and how this element enables both VCF's to function together as a single, huge filter, either in series or parallel, along with patch examples, including using the Gemini as a stereo filter.

Patch of The Week: Brass & Blade - inspired by Vangelis & Jarre, a melodic jam with 2 patches

video upload by AJH Synth Official

"First of 3 videos with the Gemini 2412, starting with this simple performance using 2 sounds derived from a monophonic synth brass patch, loosely inspired by Vangelis (Blade Runner) and Jean-Michel Jarre (specifically Oxygene). The next 2 videos will show you how to make the sounds.
The patch emulates the Oberheim SEM design (2 VCO, 1 VCF, 2 ADS envelopes), as the Gemini 2412 is based on the filter from that classic gorgeous-sounding synth module. As many will know, Vangelis famously used the CS-80, and Jarre a variety of expensive early synths, but the humble SEM wasn't necessarily associated with either of them. However, it's character of sound, and that of the Gemini, make it a particularly good choice for brass-like pads and leads, either using it's bandpass filter (as in this video), or it's high pass and low pass filters (much like the CS-80).
In the next video I'll show how to construct the brass sound from the later half of this video, and in the video following that will show how to make a couple of sounds directly based on the CS-80 patches used in Blade Runner, so stay tuned.

Check out the AJH Synth playlists for more 'Patch of The Week' videos, which will be either performances or 'how to' guides detailing a range of sounds, some familiar, some less so, and each containing a patch sheet at the end to show you how to construct it for yourself.

Patch of The Week: 'Assault on Precinct 13' Gemini 2412 Bass Cover (1976 John Carpenter soundtrack)

video upload by AJH Synth Official

"Just for fun, a patch inspired by a classic synth soundtrack from the 1970's. This time using the Gemini 2412, 1 VCO and Ring SM to create a version of John Carpenter's excellent soundtrack for his 1976 movie 'Assault on Precinct 13'. I don't know for certain, but I've a hunch that he might have used an Oberheim SEM module (or perhaps one of it's polyphonic configurations; Four Voice etc), as it sounds like one in the bass part at least, so I've used the Gemini 2412 to simulate it, since this VCF is based on the SEM filter. The SEM (Synthesizer Expander Module) was a classic 2-oscillator analogue synth module from 1975. It sounds to me like a single sawtooth being used in the movie theme, but I add an additional sub-octave using the Ring SM - it's a cover version, not an attempt to recreate it 100%.

I use the Muting Mixer for the VCA, along with it's overdrive function, to create a more aggressive, punchy bass sound, somehow more befitting a dark, low-budget thriller movie of the seventies. I also chose a reverb setting that to me sounded a little claustrophobic. Patch Notes and PDF link further down the page.

The Synth Sounds of John Carpenter: Halloween, The Fog, Assault on Precinct 13

Published on Oct 27, 2016 Reverb.com

"John Carpenter has been a master of horror, suspense, and science fiction for 40 years, Directing cult classics such as Halloween, The Thing, and Big Trouble In Little China. But many do not know that Carpenter was also the man behind the soundtracks for nearly all of his films, often using synthesizers and keyboards of the day to craft sounds that are now synonymous with Horror and Science Fiction.

In this video, Justin DeLay shows us how to approximate three classic Carpenter themes on synthesizers of the day, and gives tips and suggestions on how you can be inspired to experiment at home, all while getting followed by a mysterious Shape...

Assault On Precinct 13 Version 2.wmv
"Slightly remixed version of AOP13, the Vox Humana chords are (I think) now more faithful to the original and I've upped the Moog basses and panned them to give (hopefully) a beefier sound..

This is for Dad....RIP..28/08/35-12/08/10. I remember us so well watching this landmark film together and being blown away by both film and the music.....

Also thanks to Joeri Peters for his superb work in sampling the Polymoog's most famous preset, Vox Humana, and so generously donating it on his website...

Equipment used, Minimoog Model D, Nord Lead 3, Cubase 5, Recycle."

Sequential Circuits Model 800 Sequencer

Click here for shots via this auction.

Details: "SEQUENTIAL CIRCUITS MODEL 800 ANALOG SEQUENCER . Compatable with all analog CV and Gate synthesizers. I've discovered Dave Smith (founder of S/C) started making these units in his garage before eventually mass producing the incredible Sequential Circuits synths, drum machines (ect.) as we know them today. This is without a doubt VERY RARE ! Only 500 were made and maybe. It is in Good condition with few minor scuffs / scratches on the top and side. It has a sticker on one side from the place where it was originally sold - Rogue Music Store NY.NY. It has one broken push button (the start / record switch as shown in pic below) which can easily be replaced. The part here cost just over a dollar. You can still push it with the tip of your finger though. It Powers up and the lights come on. It counts through all 16 steps on the LED as it should. You can also walk the steps from 1 to 16. All this is done without it being hooked up to anything."

Update via Micke in the comments:
"A little bit of trivia: the original version of this sequencer:
http://www.synthmuseum.com/sequ/seqseq800ad01.jpg
was used on Earth, Wind & Fire's hit "Getaway" which was recorded back in the summer of 1976.

I was told this by LA synthesist/programmer Dan Wyman.
Mr. Wyman is perhaps best known for his synth work on multiple Giorgio Moroder productions. He´s also responsible for the Moog modular programming on John Carpenter's classic synth-scores "Assault On Precinct 13" (1976), "Halloween" (1978) and "The Fog" (1979).
