Continuing their crusade to bring free VSTi Plugins to the world Krakli Software have just released the S3K virtual monosynth.
Her'es what they say about it:
An S3 'mono' synth with a whole load of attitude. Complete with 64 excellent patches from himalaya, S3K attempts to fuse retro sounds with a hard modern edge. Octaver, Ring mod and arpeggiators are added in addition to the normal Echo, Phase and Reverb effects. For the best effect make sure that you use the modulation wheel to its full potential.
Sadly, available as a PC VSTi only
The first standalone semi-modular from Pittsburgh Modular
This crazy oscillator now has even more features
