[sdiy] VSM201 Vocorder Question

I think the "colouring" that you mention might be quite common in vocoders. I found "perfect reconstruction" very hard to achieve when designing the vocoder bands to be sufficiently selective to work well as a vocoder.

I guess a vocoder is an effect not an EQ, so perfect reconstruction can be sacrificed here. Deep notches are also far less objectionable than sharp peaks in the combined response, so I sharpened up the Q of my filters, at the expense of getting a couple of dB dips between bands.
