there is already formant shifter and bit reduction...
for shifting feed same sound to modulator and carrier in vocoder and try the shift knob. bit reduction is in scream4.
and what comes to maelstrom, it operates differently than standard granular synthesis and that way it achieves better quality, but maybe there will be sample importing with lower quality in future...
i'm quite disappointed that nobody seems to explore reasons features and usually i don't even comment on things like this.
READ the manual and think how you could achieve something before requesting feature that's already in.
sorry but i'm just little annoyed of these feature requests...nothing personal
