Hey Julien!

Well, I am an ambient composer and my use of composer has little in common with what is a vocoder typically used for (making the voice sound like a robot).
So basically, choosing a file as a modulator would be cool so that one can experiment. But having really nice waves already built in is a very good idea as well. Having both possibilities (use built-in or load your own) would be perfect.

Again, as I mentioned in the original letter, it is very much like Orange Vocoder. An example of how I used it with FL Studio back in the non-Linux days is here:

Adding nice waves to the plugin might make it more than a plugin, but more like an instrument. Allowing a person to load a carrier would make it very flexible and a unique tool.

Louigi.
