Hi guys
i have this nice piano sound that i want to use in a reggea song. The only thing that is missing is a Wahwah Fx. I can't get a wahwah sound effect on it. I'm pretty sure one should be able to program this. If any of you could just give me hint on how to do this and i'll mack around for a while. (the way to learn things

)If i can't find it, i'll get back to u guys.
Since i'm using this in a live performance, i would want to have a dedicated softknob to control the rate.
btw: i own a virus C
