Foo-YC20 is a physical modelling combo organ synthesizer. This synth is an accurate copy of the Yamaha YC20 organ, including some of the flaws found in such instruments. This project is open source and the processing code is written in a functional DSP language called FAUST. The organ is available for Linux, Mac OS X and Windows. In addition to a standalone JACK client, there’s an LV2 plug-in for Linux and VSTi for Mac OS X and Windows.
