Foo-YC20 - Free VST Combo Organ Instrument Synthesizer

Foo-YC20 – Free VST Combo Organ Instrument

Foo-YC20 free VSTi is an accurate copy of the YamahaYC20 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.

Original YC-20 organs have a touch vibrato control, which is vibrato induced by horizontal movement of the keys. As there very few (almost none) midi keyboards which produce such information, this feature has been left out of the emulation. Instead of the touch vibrato control, the control panel hosts a “realism” switch.

Foo-YC20 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.


  • Physical modelling, no polyphony restrictions.
  • Two main voice sections.
  • Switchable bass section.
  • A realism control to add flaws found in the real organ.
  • Flaws:
  • Touch vibrato is not emulated.
  • Takes quite a bit of CPU power.

Price: Free
