Dark Four is a free vst plugin that approximates a group of 4 Doepfer Dark Energy.
As suggested in the manual for the modular version A-111-5, it combines features of the DE I and II. Mod of VCF by VCO, Tri/Pulse/Saw waveforms and 4-pole Low Pass as in DE I; Multimode Filter as in DE II.
- Each module is a complete voice and contains a VCO, VCF, VCA, ADSR and two LFOs. Envelopes have two time ranges; LFOs, three rate ranges (up to audio rate).
- Each synth voice has it’s own Pitch Bend range and Glide controls, and stereo pan. For visual clarity, the modules are labeled A, B, C, D and are color-coded alternately.
- Each module’s LFO 1, Envelope and audio out can patched to any of the others.
Patching is by drop-downs at bottom of each synth voice.
