Elektrostudio did a pretty good job with Sixth Month June. Its laid out to look like a Roland Juno of some sort. It sounds like a Juno 106 or my MKS50 to me. Not super thick or punchy, but nice. The built-in chorus effect on this VSTi is not particularly lush, but it gets the job done well enough. Easy to program just like a real Juno, but very limited in its capabilities due to a stripped down feature set and fixed architecture. But when you just need some cool PWM sounds that are totally 80s, this softsynth will do the job. Its really enjoyable detuned a few cents and delayed a few miliseconds doubling an actual 80s Roland or another Roland soft-synth. Its freeware, go download it.
