Just to follow up to my last thread on this feature. Ive still had little joy with using this for vocal effects even with a preamp. In my opinion its too complicated for the results that can be acheived . Ive now (reluctently due to cost and lack of space) purchased a microkorg which has become my master keyboard and a electro harmonics V256 vocoder/autotune which ive found really simple to use. I can still route both of these back into my virus to add effects.
