Capacitance: An Oberheim OBXA Love Letter

Published on Dec 6, 2017 Dudadius

"I’m a child of the 80’s and the Oberheim synths were always a favorite. From the Police to Van Halen, it held a mythical place in my musical mind. A few years ago I stumbled on an OBXA for a really great price. It was more or less functional, but needed some love.

I installed a Kenton midi kit early on, but then the project sat dormant for a few years. I did use the synth quite a lot, including in a favorite track of mine called Heavy.

Recently, I discovered a website called Synthchaser.com that sells various rebuild kits for some classic synths, including this one. Let’s do this!

I rebuilt the clacky keyboard, replacing the bushings. Then I rebuilt the power supply. Lastly, I undertook an overhaul of all eight voice cards. There are about 20 components on each card which need replacing. It was laborious, but I actually find working with it soothing in a meditative way. Maybe it’s the solder fumes.

I just finished the rebuild and performed a very detailed calibration yesterday. I was so inspired by the new sounds this puppy was making that I realized it was time for a youtube jam!

The first sound out of the gate is the classic massive OB resonant filter sweep bass. In unison this is a sound that could start WW III. Amazing.

Next is a new sound I discovered while calibrating. No oscillators are on for this, just the resonate, tuned filters with some noise. It’s a haunting tone.

Then at :27 that sound is joined by a patch I made as an homage to Lyle Mays, Pat Metheny’s longtime keyboardist. It’s a flutey tone with the second oscillator sliding into tune via envelope modulation.

A typical string patch then sneaks in.

All of that was played ‘live’. I did program the pulsing bass that comes in, and the hi hat. Kick, snare, and hi hat are all from the OBXA as well.

The little game music bridge features a square wave-modulated lead and the standard gigantic, Prince-style brass, with over-the-top pitch bend and modulation.

I think that’s about it. Every single sound is from the OBXA!

Special thanks to Synthchaser.com for answering my numerous questions and to Old Crow for helping me troubleshoot a bum envelope chip."

TTSH demo

Published on Dec 6, 2017 Steve Castellano

"This video demonstrates some of the sonic capabilities of the TTSH ARP 2600 clone. This one is a Rev 3. Everything you hear was produced with the TTSH (with the obvious exception of my voice through the ring mod), and all reverb is from the internal spring reverb. I added a couple of effects as noted in the titles, plus basic EQ and compression in Logic."

Inside the Roland Boutique SE-02 analog synthesizer

Published on Dec 6, 2017 ranzee av

"Yep! I just voided my warranty! I take a look inside the Roland Boutique SE-02 analog synthesizer. This is the synthesizer that Roland have collaborated with Studio Electronics to make their first true analogue boutique (a move away from their usual VA/ACB style).

The video covers close-up footage of the circuit board and SMT components, including identifying chips/ICs.

All work is original without any commercial benefit from supplier or manufacturer."

WP-20 Experimental Synthesizer - Noise, FX, Drone

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

The WP-20 is an MFOS DIY synth. You can find a couple of demos and other user designs in the archives.

"Here is a quick demo of me noodling around on my custom built WP-20 Synthesizer. There is reverb added. The last 4 minutes or so are two tracks of WP-20, with one track run through the Cimmerian Caves dual echo unit + CV and Gate input from my modular system."

via this auction

"Selling my hand made WP-20 Synthesizer. Keep in mind this is hand made (etched the circuit board myself!), and it has an appearance as such (see photo's). The panel lettering is hand painted with a clear coat of varnish over top. The end cheeks are stained oak.

It can best be described as an experimental / FX / drone synthesizer. It has the following circuits:

- One VCO synthesizer (square or triangle wave) with external CV input
- One LFO (square or triange/sawtooth) with multiple destinations. It will get into audio freq.
- One loopable Envelope generator (attack & release) which can be triggered via trig button or externally and it can also loop and act as a second LFO, with multiple destinations. It will also get into audio freq.
- One VCF with Hi/Low Resonance
- One VCA
- One Noise source

I have used it in conjunction with my eurorack modular to control the pitch CV and gate input (for the Envelope generator) and it works great. It comes with a North American power supply, but will run on any 9v DC (center negative) power supply with at least 500mA

Don't expect this to act as a traditional synthesizer, its an odd little machine!"

Random Source Serge SSG Eurorack Module

See the seller's other items for more.

Side note: thought this was a pretty neat pic. Note how the wood grain lines up with the knobs and the module. It's as if the module is emanating energy, which when you think about it, technically it does.

"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."
