Software Description

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.


  • 61 keys
  • Two main voice sections
  • Switchable bass section
  • Generator + matrix mixer => no polyphony restrictions
  • A realism control to add flaws found in the real organ

There is an undocumented "easter egg". Any command line argument given to the program will be used as the configuration file name. The state of the organ controls are read from the file and the file will be overwritten with the current setup when the synthesizer is shut down.

New in v1.2.1

  • Denormal protection for the LV2 and VST plugins was left out by mistake from the 1.2.0 release. Version 1.2.1 fixes this

New in v1.2.0

  • LV2 plugin
  • VSTi plugin (and standalone Jack client) for Windows
  • OS X build (standalone Jack client)
  • Improved volume control curve
  • Fixed bug with 4' drawbar bleed
  • More subtle hover highlights
  • Switch GUI to use GTK directly without GTKmm
