If, like me, you're far too cheap to save up for a Sidstation but still like the idea of making music that sounds like it was composed on a Commodore 64, the Retro-GS01 is the VST synth for you. It was created by Saul and Gary at Simple Media, who've made a few interesting little things, including a virtual theremin, and a whistle synthesiser.
