The main differences between Version II and III are an improved VCO (no warm-up period, additional triangle waveform, wider frequency range), resettable LFOs, improved ADSR and a lot of internal access points for DIYers. The favored filter of the Dark Energy II has been unchanged. Dark Energy III is a monophonic stand-alone synthesizer with USB and Midi interface. The sound generation and all modulation sources are still 100% analog, only the USB/Midi interface contains digital components.
The Unit should be released in a couple of weeks – the spring will be darker – oh yeah.
