hello florian,

it can sound really good, but not with all signals.
i like to use the pause stuffing with pad sounds as
carrier and another synth sound as modulator.
the pad sound is sustained even without the presence
of the modulator, and changes dynamically when the
modulator starts playing. not the standard use, but fun :)

as always with vocoders, the result is heavily dependent
on the used signals. of course the self vocoding will
change the overtones of the modulator at the output,
but from my understanding that is intentional.
this way the vocoder will provide a vocoded sounding
signal even when the modulator is silent.
some time ago i used an electro-harmonix vocoder which
offered pause stuffing. i don't know if ems uses a
different term or method, but on the electro-harmonix
it worked that way. i think it also had a compressor
built-in to tame the wobbliness. of course my patch is
only the "simple" version. i didn't want to make things too
complicated, so i kept it as simple as possible, only
to show the working principle. it can be improved with an
additional compressor patch, but i found that this is not
always necessary, as long as you use synth sounds only.
with a human voice this is of course a different story.
a human voice really needs compression to give good results.
