Cryabetes –

Thanks. So, if I understand correctly, guitar effect pedals (and particularly the Stereo Talking Machine and Micro Synth) are monophonic and they are triggered by each new, louder volume change. That is, every time the pedal senses more amplitude, voltage or volume, the envelope re-starts which is why these pedals work best on a monophonic, plucked (picked or strummed) guitar (or harp). And which is why they will perform differently if the instrument is wind (clarinet or voice for example) where the initial attack may be slow and increase and continually re-start the envelope or if the instrument is polyphonic (accordion) where the pedal envelope doesn’t know which tone to process since it’s monophonic.

Which is not to say that the result will be undesirable but only that it will be less predictable. And so, the only way to really know what the processed sound will be is to get a pedal and experiment.
