Hudson Mohawke. Dark Energy I The Dark Energy is a compact, monophonic, analog desktop synthesizer module produced. At the time of the Dark Energy's launch in 2009, Doepfer was perhaps best known as a manufacturer of Eurorack modular systems. The Dark Energy owes its existence directly to Doepfer's modular products, it is the module in a rugged, fully-enclosed metal housing.

Whereas the A-111-5 has the usual silver finish of Doepfer modules, the Dark Energy's case is an attractive black finish with retro-style black knobs, toggle switches and wooden end panels. The Dark Energy is a single oscillator synth capable of producing square/pulse, triangle or sawtooth waveforms. The square/pulse wave can be used on its own or in conjunction with the triangle or sawtooth waveforms. The triangle and sawtooth waveforms can also be used individually, but it's not possible to use triangle and sawtooth together. The Dark Energy has two LFOs, both capable of triangle or square waves. Each LFO has a range switch for low, medium or high frequency ranges, allowing for very slow modulation, through traditional LFO settings, right up into the audio range (to about 5 kHz) allowing for audio-rate frequency modulation.
