HT8950 "robot voice" Eurorack Module Build


Published on Oct 20, 2019 Reckless Experimentation Audio LLC

"I take a Holtek HT8950 voice modulation chip and turn it into a Eurorack module. I found the best spot in your signal path for this module is between the VCO and the VCA, acting as an 'overdrive' effect."

E&MM Spectrum Synthesiser Preview


Published on Oct 20, 2019 Reuben Jones

"The E&MM Spectrum is a British DIY synthesizer designed by Chris jordan and released with Electronics and Music Maker magazine in 1981.....

The magazine provided a painted metal faceplate, keyboard assembly, and printed circuits boards. The rest was sourced by the builder using a supply kit provided by the now defunct Maplin Electronic Ltd, UK (see also the Maplin/ETI 3600, 3800, 4600, and 5600S synthesizers).

The synthesizer uses the famed Curtis integrated circuits: VCOs (CEM 3340), VCF (CEM 3320), VCA (CEM 3330), and envelopes (CEM 3310). These chips were used by many companies at the time, including AKAI, ELKA, Ensoniq, Oberheim, Roland, and Sequential Circuits.

Perhaps the closest synthesizer to the Spectrum is the Sequential Circuits Pro~One, both of which use the same CEM chips for VCOs, filter, and envelope; and use a similar two-VCO architecture. However, whilst the Pro~One is known for an extensive modulation section, the Spectrum is very interesting in its own right.

The design makes the most of the CEM 3340 VCOs, with a total of five waveforms, including a SUB square wave. The LFO, with multiple waveforms including random and regular sample and hold (the latter of which produces more defined sequencer like voltages), can be routed in positive or negative polarity to the VCOs, filter, ringmod/noise, and output. The multimode LP, LBP and BP filter is a self oscillating one and can be modulated by the joystick, envelope generator, and the LFO. There are also two sync options, as well as FM, ring mod, and an envelope shaper. The stereo output can also be modulated for panning and stereo FX; and there are eight jacks for external connectivity including CV/Gate in and out, and pre filter in.

In conclusion, I would describe the Spectrum as a drunk and wonky Pro~One. Mine is temperamental, and sometimes has a mind of its own, but when tamed, the Spectrum becomes a very live and organic synthesizer. The tech who serviced it for me said it reminded him of an ARP 2600, and described it as a 'proper synth'. GreatSynthesizers.com describe it as "...a mixture of EMS Synthi, Sequential Pro-One and Roland SH-5" and "one of the most outstanding monophonic analog synthesizers in history".

This audio was recorded directly from the Spectrum in mono, using a TC Electronic Alter Ego delay pedal for some parts. All parts played from the keyboard, or using the LFO to gate the amplifier."

'Analog Ambient' Performance 2 - AJH Synth MiniMod Eurorack Modular


Published on Oct 20, 2019 DreamsOfWires

"All-analogue 2-voice synth performance/improvisation, part 2 of a series of work-in-progress recordings for a future album/release. No overdubs, just 2 patches/parts played simultaneously. Turn on subtitles for a rundown on what's happening. See the previous composition/performance here: [posted here]

The AJH Synth 'Mini Mod' Eururack modular system is like the Moog Modular I could never afford, only better, as it benefits from modern design features, is a fraction of the price, and a fraction of the size. It produces those rich, warm, characterful tones of the 70's I always wanted, and so much more.

Recorded on an iPad using AUM, with EOS2 reverb.

5 Patchlets with Freak from Vult


Published on Oct 20, 2019 Omri Cohen

"Five little patches I've recorded with the hardware version of Freak from Vult, a stereo multi-mode digital filter. There is no processing what so ever to the sound, no compression, EQ, distortion, or whatnot. The only thing added is a limiter to keep the levels from clipping.

Black Corporation Kimji SN 1278


via this auction

"Folks this is a really cool piece. I took this in recently as part of a large gear swap. There was a lot of buzz last year about this synth called Kimji by Black Corporation of Japan. I believe they may have only made 10 or so of these as part of a very limited initial run. This is serial number 1278. It includes the original box. There is no physical manual but there is one accessible online. The unit is in mint condition and the pictures are of the actual unit you will unbox.
The Black Corporation Kijimi is a faithful recreation of the very rare and highly sought after French wonder-synth the RSF Polykobol. Originally released in 1979 the PolyKobol MK1 was restricted to only 30 units worldwide and is considered to be one of those most significant synths developed in this era.

Kijimi is an 8 voice polyphonic synthesizer with two continuously variable oscillators per voice, an incredible modulation section, MPE compatibility, preset storage and recall and build quality that is enviable to say the very least.

Kijimi’s inspiration, the Polykobol was a synth that was very much ahead of its time, providing a wealth of unique features and tone shaping options that even to this day stand out, such as the continuously variable wave shaping, open and easily assignable modulation section with 5 sources and multiple destinations and a rich, interesting filter tone.

Owning an original RSF Polykobol is, even for the most diehard collector almost impossible. Just like with their Deckards Dream CS-80 inspired powerhouse, Black Corporation have again made one of the most inaccessible synths, accessible for everyone.

Kijimi is another standout synthesizer from Black Corporation, delivering the sound quality, aesthetics and workflow of a Polykobol with all the mod cons you’d expect from a modern machine.

The main features of the Black Corporation Kijimi include

8 voice polyphonic analogue synthesizer
Inspired by the legendary RSF Polykobol
CRN3340 based VCO’s
SSM2040 based vilter
Polyphonic aftertouch
MPE compatible"

Crow: First (Monome Crow + Mannequins)


Published on Oct 20, 2019 S. B. Arweiler

"First flight with Monome Crow. This is Crow's 'first' sequencer, sequencing Mannequins Mangrove and a self oscillating Three Sisters. Just Friends is only used as a clock source in this patch. Everything goes through Bastl Thyme. EHX Catehdral adds reverb in the mixer's."


via monome

"crow speaks and listens and remembers bits of text. A scriptable USB-CV-ii machine.

crow connects to norns and computers running Max, Max for Live, and other serial-enabled applications. We’ve created various norns scripts and Max for Live devices which require no programming, and we’ve also created tutorials and studies to get you started quickly programming your own ideas into this tiny, powerful module.

crow also stores a complete script, so that without a USB connection it can continue to run, responding to CV input and ii messages.

A collaboration by Whimsical Raps and monome.

warmth | Digitone + Analog Heat MK2 Dark Ambient


Published on Oct 20, 2019 Blicero

"warmth by Blicero

I recently sold a lot of stuff to downsize my set-up and in doing so acquired an Elektron Analog Heat MK 2. Which is far and away the most musical and wonderful distortion/Drive I’ve worked with. I really like on certain settings that you can sit at the precipice of a destructive effect without going to far in.

This piece was made on the Digitone straight into the analog heat. A little darker in tone than previous stuff; I’d expect a little more of this kind of thing moving forward. It’s inspired by my days of post-rock and shoegaze guitar playing.

Recorded onto a Zoom H6 and lightly processed in Ableton."

ARP Omni 2 SN 1144


via this auction

"This is an ARP Omni 2, Model 2473, fully overhauled by Synthcave Sound. It's fully functional and sounding great! The legendary Omni 2 is perhaps most closely associated with Joy Division but was used extensively in numerous recordings in the late 70s and early 80s. Its lush Solina string-ensemble sound is much sought after, but the Omni 2 also features a polyphonic synthesizer with VCF, LFO, and ADSR envelope along with a separate bass-synth section with its own envelope. Comes with a power cord.

The just-finished restoration consisted of 40+ hours of work:
- All 15 sliders were replaced with brand-new, modern, LED-illuminated sliders; these are super-smooth and look fantastic!
- All tantalum and electrolytic capacitors in the power supply have been replaced with brand-new, high-quality, high-voltage electrolytic capacitors - additionally, the recommended power-supply mod as described in ARP's field change notice FCN0011 (addition of a pair of capacitors and a pair of zener diodes) has been performed
- New key bushings on all keys, buss bar cleaned, and the keybed leveled
- All tantalum capacitors throughout the synth have been replaced with new high-quality electrolytics
- The 4075 VCF module has been modded for improved cutoff range
- Fully calibrated to factory spec with oscilloscope and frequency counter

Cosmetically, the synth is in quite good shape, considering its age. The top is a little scuffed up, as is quite common for the Omni 2, as people tend to like to set things on them that they probably shouldn't due to the flat surface. But, overall, it looks great, particularly with the new illuminated sliders!"
