Another really good synth VST from Togu audio that I'd put up thee with Automat and Crystal Synth. Its a decent replication of the Roland Sh-101 (hey you can't beat the price), which is definitely one of my favorite sounding/most fun to play synths. Togu also makes a great juno sounding synth and a really nice dub delay, so check out their other (free) plugins.
