StudioFactory provides a complete virtual audio studio on your computer. It has a very powerful virtual analog modular synthesizer based on an improved version of the SynFactory synthesis engine. StudioFactory is fully compatible with SynFactory and can load all existing patch files. The synthesis engine is extended with additional modules that give access to MIDI and audio input. This makes it possible to play sounds generated by StudioFactory with an external MIDI-keyboard.
