Hey

I was fiddling with a vocoder the other day and I couldn't figure out how to get the sound the guy needed. All that i could do was make a voice sound all robot-y in a bunch of different ways. He wanted the tone of the voice to sound the same, but just the pitch to change.

I worked long and hard to earn a reputation in my college as the TOP-DOG engineer, that bloody thing made me look a fool HAHA. Anyone know what im doin wrong?

i dont understand what you mean what vocoder are you using and what software? cant the vocalist sing like it naturally instead of changing the raw recording?

Try something like Audacity, (free!)
One of its main effects is pitch change without changing the speed.
