I am currently being enticed by the COTK voice coding processor and 
the Bode frequency shifter. I am wondering if anyone on this list has 
experience with the said modules. I would also be willing to look at 
other analog vocoding gear if anyone knows af any.

And I have a question about the bode frequncy shifter. would this 
module be able to create effects such as high pitched elf speech? is 
frequency shifting very diffent from digital pitch shifting? any 
insight would be appreciated.
