Update: The listing has the FAEMI-M as being from 1968. It seemed a little early to me so I checked my copy of Peter Forest's The A-Z of Analogue Synthesisers. It's listed but without a production date. Right before the entry for the FAEMI-M is the FAEMI children's keyboard which was released in 1972. I then checked http://www.ruskeys.net, but no date is given either. Previous posts refer to the FAEMI-M being from the 1970s. Sound on Sound's article on the Polivoks mentions the FAEMI-M but w/o a date. If anyone defininitively knows, feel free to leave a comment. A couple of interesting comments from that Sound on Sound article:

"The Polivoks is a duophonic synthesizer designed by Vladimir Kuzmin, an electronics engineer who had been the bass player and sound engineer in his student band. Having graduated in 1976, he was inspired to apply for work at the Urals Vector Company by the inventor of the FAEMI, the first commercially successful Russian electronic keyboard. That man was Vladimir Lugovetz, the Director of the bureau that controlled development of electronic instruments at the Vector company, and the father of Kuzmin's future wife."

Followed by "Interviewed by Polish synthesizer enthusiast and supplier Maciej Polak, in 2003, Kuzmin explained: "My first task was to design the spring reverberator, but I also tried to improve the design of FAEMI‑M in order to obtain some modern effects such as portamento and filtering."

Auction details:

"So, the good news: All four oscillator generators are working; I have cleaned the potentiometers, and only one couldn't be fixed, and just one is slightly crackling on movement. I replaced the output jacks with the standard 1/4" jack.

Things I couldn't fix: The vibrato section is not working. Several keys are not working at all, and some of them work when pressed harder.

The external original power supply is unusual – it is combined with the scale pedal in one housing. The pedal works, but it also has a slight crackle on movement.

To see and understand the objective condition, I recorded a video. Please watch below, where I aim to show the specific condition of the device. Despite the problems, it is still alive, and I believe you can either repair, sample, or simply enjoy the time with such an old and unusual synthesizer, even in its current state. Of course, due to these reasons, I have also objectively reduced the price.

The package is fully loaded: synthesizer, original power supply/volume pedal, original 5-Din cable to connect the pedal to the synth, power cable for the power supply, original wooden hard case

Here is some official spoecifications:

Specifications:

Keyboard volume - 4 octaves.

Full sound range (all the registers are switched on) - from F in the controctave to E in the fifth octave.

Output voltage at the load of 100 kOhm - not less than 0.1 V.

Power supply:

Power consumption from AC mains - not more than 15 W.

Current consumed from the battery of dry elements - 350 mA.

Overall dimensions - 610*280*110 mm.

Weight - not more than 10 kg."

RS060 Dr Böhm Dynamic 12/24 (Orla DSE): German EFF EHM

video upload by rejected synths

"Talking synths from Germany, quite a few companies come to mind: Waldorf, Doepfer or Vermona are popular ones still around and there are a lot more, some of them long gone like pioneering PPG. One company that hardly ever makes the list is Dr Böhm Organ. This might be down to the fact that Böhm weren’t exactly a company focused on synths at all but rather one that offered DIY kits for people to build themselves electronic organs.

Strictly speaking these organs were ‘synths’ too and when the 80s arrived, Böhm, just like companies like Sequential, Roland or Yamaha, started to utilize digital control and later digital synthesis in their ‘synths’ too, albeit utilizing interfaces more akin to traditional organs.

One other similarity to ‘real’ synth companies was that they also started to offer expander modules, that could be controlled by midi, expanding the variety of sounds while at the same time saving on space (no keyboard) and costs.

This is where today’s synth comes from. The Dynamic 12/24 was meant as an affordable way for Böhm’s customers of home owners and entertainers to expand their setup with some more organ but also other sounds like strings, e-pianos and some 80s-ish synth staples.

The technology used was taken from one of it’s electronic organs and while clearly trying to hide it (even going as far as filing the markings off the ICs) it was Yamaha FM Chips doing Yamaha sounding 4OP FM. The good thing is of course, that this is actually a great basis for a very wide range of sounds, especially as Böhm was kind enough to add user memory to enable creation and saving of your own patches. Also, editing can be done via midi and there are editors available too. What makes the 12/24 stand out from the crowd of 4 OP modules most though is the unique Böhm analog bucket brigade delay style ensemble effect, that ‘warms’ the FM sound.

Last but not least, the Dynamic 12/24s seem to be widely available and dirt cheap too, at least here in and around Germany. So grab one before they become cool, or anyone finds out they are actually the same as the Orla DSE, a synth that has been used by a guy that goes by the name of Richard David James…"
