Using filters etc. directly?

[danja]

I'm just about to go poking around in the libs, but I thought I'd ping you first. I'm not exactly hot on C++ so it'll probably save me time in the long run :)

Anyhow, I want to make something like this 1979 analog gadget but based on the Arduino, it's essentially a joystick & some switches hooked up to a oscillator, noise generator and a couple of formant filters:

(I stumbled on the article by accident, bizarrely I remember reading it in the original magazine, thinking - want!).

So if I wanted to take input from, say, a couple of joysticks and use that to control oscillator & filter freq, which bits of the libs would I need to look at?

What I'm after, Talkie is way too sophisticated for :)
I'd like to be able to manually make speech-like noises, that almost certainly won't be words.

I'm very impressed by what you've put together - had to do the const tweak, but essentially the examples worked out of the box.
