Notes Once again the differences between Dark Energy I and II as summary:

12dB multimode filter with lowpass, notch, highpass and bandpass (instead of 24dB lowpass of Dark Energy I)

the previous LM control of the filter becomes the filter type control Mode (continuous crossfade lowpass - notch - highpass - bandpass)

the modulation level control of the filter "XFM" has so-called "polarizer" function. The modulation source (LFO2 or ADSR) selected by the Source switch may affect the filter frequency in a positive (right half of the control range) or negative way (left half of the control range)

the waveform switch is used to select between saw and clipped, inverted saw (in the center position the saw is off)

the basic waveform of the VCO is saw (not triangle like the Dark Energy I).

the VCA has a exponential scale (not the combined linear/exponential scale of Dark Energy I)

because of the pure analog circuit and the temperature control it may take up to 20-30 minutes until the VCO is in tune.

The sound of the Dark Energy II differs clearly from the Dark Energy I (mainly because of the completely different filter type). If you already own a Dark Energy I the Dark Energy II can be used as an expansion. But you will not be able to copy sounds of the Dark Energy I with the Dark Energy II (and vice versa) !

For users with electronic knowledge the Dark Energy II offers much more internal expansion features than the Dark Energy I. For example terminals (pin headers) for these features are available: VCO Hard Sync, linear VCO FM, rectangle and sawtoooth output of the VCO, lowpass/bandpass/highpass output of the VC, Reset/Sync/Direction for each LFO, rectangle and triangle output for each LFO. In addition an improved version of the glide option is is the planning stage that allows to turn on/off the glide function via Midi control change messages.
