I bought Filterscape recently and noticed on the website that it says that Vocoder like effects can be acchieved, yet I haven't been able to do so. Does anyone have a preset or can help me make one?
thnx
Using Filterscape as a Vocoder, how?

Yo,
The Vocoder-like effects are basically formant filters.
A Vocoder works like this:
- an audio signal A (commonly human voice) is analysed by spliting it into x formants/bands and following their envelope
- another signal B (usually harmonically rich such as a sawtooth or a distorted guitar) is fed through x parallel bandpass filters that match the bands above and get the envelopes applied
- the result is, the formants of signal A are applied to signal B - the guitar "talks"
- x may be in the 10s to 20ties
Classical vocoder plugins (i.e. Orange Vocoder) get signal A as input, and produce a sawtooth etc. internally. This is one flavour of vocoder-style, but it's just one possibility. Filterscape works differently.
Filterscape provides you with up to six bandpass filters (as opposed to x) in parallel that can twirl around like no vocoder can (vocoder filters typically have fixed frequencies while Filterscape's can vary dramatically). Thus, with Filterscape you can manually create format movements like in a vocoder and apply it to any kind of signal. It's somewhat "the other way round" from classical vocoder plugs.
There are some presets like "Yeah Yeah Yeah"... try these on drumloops or trance synths
Cheers,
