Cygnus-SF
SoundFont variant of Cygnus-O
Another version of Cygnus, with the extra functionality of being able to load Soundfonts ito each of the 3 oscillator locations, this feature coming about due to the plug-ins coverage at GearWire.com.
All three versions of Cygnus are semi-patch compatible (with the proviso that the original "space" Cygnus will not be able to load patches created in the SF version without displaying an error) and will happily live alongside each other in your plug-ins folder.
