Doepfer Dark Energy 2 Synthesizer

As the Dark Energy (I) had to be discontinued because an important electronic part (CEM3394) is no longer available we decided to do a redesign of the Dark Energy. The new Dark Energy II looks like the Dark Energy I at first sight. But the basic sound of Dark Energy II is clearly different from version I because of the new circuits for VCO, VCF and VCA

Dark Energy II is a monophonic stand-alone synthesizer with USB and Midi interface. The sound generation and all modulation sources are 100% analog, only the USB/Midi interface contains digital components. Dark Energy is built into a rugged black metal case with wooden side plates. High quality potentiometers with metal shafts are used and each potentiometer – except the filter mode control – is fixed to the case (no wobbly shafts and knobs). The distance between the controls is a bit wider compared to A-100 modules and knobs with vintage look are used.

Only the first device has to be connected to the Midi or USB transmitter. For this purpose the side plates of the metal case are equipped with holes that allow the internal connection of 2 or more Dark Energy devices. For this the metal cases have to be mounted directly to each other without wooden sideplate between the units. If a wooden side plate is desired between the devices one has to drill a hole to enable the internal connection.
