The Doepfer Dark Energy Mk I was one of the first entry-level modular synths of the modern era, featuring an array of voltage in/out jacks for its synthesis features. Superseded by the Mk II in 2012, the original Mk I has become a collectors item thanks to its 24 db/oct Curtis filter.

The DE1 Collection includes:

• 4 multisampled 5-octave Dark Energy instruments
  • Bass, Pad, Lead, and Pluck
• 48 synth presets (24 w/integrated effects)
• 4 flexible effects racks
• 24 effects presets
• 20 royalty-free MIDI loops
