I just ran across an article on Softube Modular... oddly (to me at least since I prefer hardware) - seems kind of interesting how they are recreating specific modules. http://www.softube.com/index.php?id=modular
"Created in close collaboration with Doepfer, Softube Modular gives you both the sound, flexibility and expandability of a true analog modular synthesizer. But Softube Modular is more than just another virtual synthesizer plug-in—it's an entirely new modular synth standard."
"Basic system contains six Doepfer modules (A-110-1 VCO, A-108 VCF, A-132-3 Dual VCA, A-140 ADSR, A-118 Noise/Random, A-147 VCLFO)
Basic system also contains over 20 Utility modules (such as MIDI to CV/gate, mixers, slew, sample & hold, switches, multiples, delay, offset, sequencers, clock dividers, logic and signal tools, as well as a Polyphonic MIDI to CV/gate module).
Additional authorized emulations from Intellijel is available as add-ons (uFold II, Korgasmatron II, Rubicon). Many more modules from other quality hardware Eurorack vendors to be released"
