Synovatron CVGT1 Eurorack-to-Buchla Converter

If you want to control a Buchla modular synthesizer with your Eurorack (or your Eurorack with a Buchla!) you should know that Buchla uses a different Volts-per-octave ratio as the Eurorack synthesizers, that work on a standard 1 Volts/Oct.
Buchla's pitch CV scaling conforms to neither the common 1V-per-octave or Volt-per-Hz (Roland) standards.

Buchlas generally conform to 1.2V/Octave (100mV/semitone) but older systems have 2V/octave scaling e.g. 258.
The other voltages lie in standard regions.  Control voltages and timing pulses of the Buchla are +5V (signals with sustain) and +10V (transients only), and should be compatible with most other manufacturers' devices.
Besides that, Eurorack uses 3.5mm mini jack sockets and Buchla uses 4mm banana sockets.

Synovatron's latest module is a Eurorack format Eurorack/Buchla translator called CVGT1.
It was launched a few months ago at the Brighton Modular Meet at the University of Sussex just outside Brighton UK. The 8 HP wide module a…

RIP Joop Stokkermans

Last week on the 25th of October, Dutch composer, piano player and (ARP) synth-pioneer Joop Stokkermans died at the age of 75

Stokkermans was an extremely important contributor to Dutch TV music, radio music and commercials from the early 60s into the late 90s.
Although he is mainly known as a pianist, but he also had a great interest for synthesizers since they first appeared.

In 1970 he recorded a full album on the only working ARP available in Europe at the time, together with help from technician Roddy de Hillster who programmed most of the sounds.

The album contains re-arrangements of standards from classical Bach (Air) and Tchaikovsky (The Swan) compositions, re-arrangement from Bacherach, Paige and Becaud and some compositions of his own.
Together with a full orchestra conducted by Bert Paige this turned out to be a very interesting and maybe even groundbreaking album in Dutch synthesizer-music.

Doepfer and Vostok Live Modular Music Part 1 and 2

A pair of fresh random videos from YouTube again.
I picked these 2 today, sadly without live-video, but with great soundtracks.
Composed with Doepfer and Vostok modular systems... and much more*.
Watch the slideshows.

Video 1: Doepfer and Vostok Live Modular Music Part 1

Video 2: Doepfer and Vostok Live Modular Music Part 2

* After posting these videos, the creator of these tracks (Marvin Wilson) mailed we with some extra info:
" I made the two tracks using just the modular stuff, recorded live as i always do. On part one the dark energy's produce the drum sounds... sounds a little like the old roland TR77 or 55... while the a100 did the bass and top line, the vostok also producing the mid sounds plus the ems style fx...

Part two the vostok does some processing of voices from tape while the dark energy's do the high resonating sounds and finally the a100 the squelchy bass, both make heavy use of the analog sequencers run in tandem.  Thought i would put two contrasting tracks …

Doepfer MS-404

In December 1994, Doepfer released the Doepfer MS-404
The MS-404 is a MIDI analog synthesizer with a 24db resonant filter that Dieter Doepfer intentionally created for his own personal pleasure earlier that year.

In the summer of 1994 he created a monophonic analog synthesizer in a 19-inch rackformat / 1 unit high.
Although his module could do so much more than reproducing the sound of a TB-303, most consumers looked at it as an extended clone of the classic Roland TB-303 bassline.

Its two LFOs (that can modulate the single VCO) add a lot extra to the original 303 functionality.
Other extra features include a full ADSR envelope generator, noise, FM and PWM capabilities, an external filter input, CV/GATE interfaces, MIDI implementation and a glide effect.
The MS-404 can be played via MIDI but all parameters are controlled manually only.
The slide and accent effects from the TB-303 are possible on the MS-404 via glide control and it uses MIDI velocity for accent.

The price was around 30…

New BNC Connectors For A-178 Theremin Antenna

It's good to see that Doepfer also keeps improving the older modules.
I already complained in July 2011 about the lousy connector of the A-178 Theremin antennas
(read the post HERE), and look now what they recently announced:

" From August 2012 an improved version for the antenna connector is used.
A so-called BNC connector is used to connect the antenna to the module (same type of connector as used in measuring equipment like oscilloscopes)."

The new version of the module is so brand new that it still has to be sent to Doepfer's photographer for taking pictures.
The new model seems to have a completely different front panel and pc board.

If you are experienced with DIY you may replace the 3.5 mm socket by a BNC socket yourself and increase the diameter for the new connector in the front panel, but you can also place it parallel to the original antenna socket at the same height, but more to the right where there is more space behind the front-panel (at the other side o…

SiteTip: Waveform City

Another interesting site that i only recently discovered is WaveForm City.

Waveform City produces and publishes interviews with synth-manufacturers and influential people in the field of analog synthesizers.
Pretty interesting stuff... so far they published 14 episodes since the beginning of this year.
They have already posted interviews with Harvestman, WMD, Make Noise, Mark Verbos, Richard Devine, Tom Erbe and many others, i hope they will interview Dieter soon...

You can find all interviews at:

You can also follow Waveform City on SoundCloud via

Doepfer A-154 Sequencer Controller Videos by Raul Pena

After Raul Pena's A-155 Analog/Trigger Sequencer videos from last month,
the only logic follow-up to that series had to be about this next module.

The A-154 is an expansion module for the A-155 that offers a lot of extra features that are not available in the basic control unit of the A-155.
Up to 2 A-155 modules can be controlled by this module.

YouTube Tip: MrWogie's Channel

Okay... i was kind of excited when i accidentally landed on THIS obscure YouTube channel, and to be honest... i still am (a bit).

There is not a lot of info accompanying the videos, but YouTuber MrWogie (Wolfgang Giesecke) uploads a lot of analog/modular studies, soundscapes, drones, very cool modular synth improvisations and other interesting analog compositions.
A bit weird for some perhaps, but sonic p*rn for some.

All uploads are mainly audio, but a lot of his videos have a slow slideshow showing some pictures of (assumably) his setup.
His latest videos seem to involve a very nice system (A-100, Dark Energy, Yamaha EMP100 effects, and several PC's running virtual synths).
It sounds like MrWogie is a classically trained musician, you will also find orchestral music in his YouTube stream.

The weirdest thing in my opinion is that these videos hardly have been viewed or played.
I'm sure you'll like them if you're an analog music fan like me.
Here's a …

Dark Energy II Coming Soon

It looks like the long-awaited Dark Energy II will almost see the daylight.
Doepfer receives the first batch of pre-serial Dark Energy II models any time now...

After these models are tested and checked (and no major flaws are discovered), the first production-order will be placed and Doepfer can start distributing the first modules.*
A part of that first production-batch is reserved for people who pre-ordered their DEII.

To fresh you up, the main differences between the Dark Energy II and the original Dark Energy are:

- 12dB multimode filter with lowpass, notch, highpass and bandpass (instead of 24dB lowpass of Dark Energy I)
- the previous LM control of the filter becomes the filter type control (continuous crossfade lowpass - notch highpass - bandpass)
- the LM function of the filter is no longer available
- the waveform switch is used to select between saw and clipped/distorted saw (in the center position the saw is off)
- the basic waveform of the VCO is saw (not triangle like th…

Modular In A Picture Frame

A great idea for a nice modular case can be found on

This project by Andrew Dobbels involves a real picture-frame and a 208 HP Eurorack with various modules.
You can find the making-of pictures on his site with explanatory texts, so you can build your own.
