selling my Doepfer Dark Energy I synth!

switchin up my synth setup so i'm sadly letting this go

operable w 12-15v AC 400 mA psu (not included)

from vintagesynth :

"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. The synth's single ADSR envelope generator also has a range switch, so the envelope can vary from very short and snappy to very long and slowly evolving.

The VCO frequency can be modulated either by LFO1 or the envelope, whilst the continuously variable pulse-width can be modulated by LFO2 or the envelope. With the LFOs set in the audio range, interesting FM sounds can be achieved, but unfortunately the LFO frequency cannot track the keyboard. The VCA level can be increased so that drones can be produced, or it can be controlled by the envelope or LFO1, again with filter FM capabilities with the LFO on the high setting.

The filter is a 24 dB/octave Curtis filter with VCO tracking, which can be set to off, half or full tracking. The filter resonance can be turned up such that the filter self-oscillates, allowing a sine-wave sound to be blended in with the other waveforms. The tracking is not as precise as the VCO and it is not temperature compensated, but the sine tracks pretty well over a couple of octaves without adjustment.

The filter cut-off can be controlled either by the envelope or LFO2, the level control being labelled XFM for exponential frequency modulation. The control labelled LFM provides linear audio-rate frequency modulation of the VCF by the triangle waveform of the VCO allowing for other rich sounds."
