foo-yc20 YC-20 - Yamaha organ emulation

The YC-20 is a divide-down combo organ designed in the late 60's. This emulation faithfully copies the features, sounds and flaws of the original organ. For Windows and OS X VSTi plugins with the proper GUI.


  • Physical modelling, no polyphony restrictions
  • 61 keys
  • Two main voice sections
  • Switchable bass section
  • A realism control to add flaws found in the real organ


  • Takes quite a bit of CPU power
  • No touch vibrato
The emulation is written in Faust. The standalone application uses Jack for audio and MIDI and is available for Linux Windows and OS X. There is a LV2 plugin for Linux and a VST for OS X and Windows.
