Solcito Musica has released version 1.1 of SuperSonico, a virtual analog - additive synthesizer for Windows. The stand-alone version is free. The VSTi plug-in version costs $8.
Here's what they say: "The digital nature of virtual developments allowed to include additive synthesis functions and precise control of phase, conserving the architecture and sound of analog synthesis."
It has a generator of overtones that can be detuned from each other and adjusted to different scale intervals to make fat sounds and one-finger chords. The Sub-Oscillator includes an option that generates a single low octave that is repeated along the keyboard. The functions of the modulation wheel can be handled by a pedal, useful to handle effects like Leslie-style and others. The"Fast Help": When doing a click on some controls or zones, it will appear a contextual help.
