MOTM

OK, so I'm on a vocal formant kick.

Someone somewhere asked what the settings on a 410 would be to do 
vocal formants.  My first thought was, well you can't because there 
is not enough resonance to get good formants.  Then I thought, wait 
aminute, how about feeding the output back to the input with a mult?

Has anyone tried this?  I will when I get home, but I was wondering 
if someone has already done this.  What was the outcome?
