Your favourite synth(-plugin) does not have the sound of the famous Roland™ Supersaw™? This audio effect will fake it for you! Place it behind you synth in the audio chain or route any other signal thru it. When feeded with a saw wave, the output will sound like a Superwave. But every other signal will also do it. Superfake is more than a chorus. It delivers six detuned voices, which can be spread in the stereo field. The amount of detuning can be adjusted for a wide range of applications.
Superfake is free! (just a message screen at startup, no limitations, adware, spyware or toolbars). Available for Windows as 32bit VST.
