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

"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…"
