I want that sound, how to describe it? Grainy, hollowed-out, micro-swiss-cheesed, aliased? I just want my notes to sound that way *without* recording them, slowing down the recording (and pitching them way down often times) and then playing them back, no matter how quickly, or even preciently, that process can be operated. So, timestretch sound-quality/timbre/whatever-the-fuck-that-sound(!) without stretching any little times....
How would you cobble together something like that?
Light SRR? A little bit of clipping? Comb filter? Frequency shifter? Run the signal through successive octave ups and downs? Use a crossover to do some of that to only one part of the frequency spectrum?
How???
