Each track is done with one specific synth to create all instruments. It's KVR's OneSynthChallenge that made them manifest. The majority of synths are free vst instruments from the web. It's quite amazing what beauty waits for you to just download it and have at it.
All of them are done with my favorite DAW: MuLab (www.mutools.com)

One Synth Only

Taron - Prognosis [ExtraBold]

17 instances of PG8X (64bit).
Effects are all MUX patches (Mulab's internal modular system): 
2 reverbs ("freeverb.mux", "tight room.mux")
2 delays ("OnBeat.mux", "PingPongBeat"),
1 compressor (which I still can't handle in mulab for some reason).
No plugins.

My first One Synth Challenge and my first conscious exposure to the KVR crowd of most excellent musicians! I'm rather intimidated by the professional quality around here and just such seasoned clarity in the mixes. I'm almost ashamed to post mine, but well... it's been fun to wrestle with this beast.
