so this first question is about synthesis, not modification for
effects, right? and real-time, correct? so a MIDI Note-On is
received and you want a note coming out as quickly as possible?
i don't know of a hardware product that does inverse FFT for
synthesis. i do know of a couple of effects algorithms that go into
products that use FFT. i think it's mostly about doing "fast
convolution" for purposes of reverb.
what are you intending to synthesize? notes? or something more wild
than that? just curious.
basically a sample "mangler", you load an arbitray sample, a loop of
music for instance, and play back parts of it in real time,
time streched, pitch shifted, with formants corrected or altered,
I dont need polyphonic playback, though that would be nice for some
right now I do this with a granular "cloud", that is many overlapping
grains, which can play polyphonic
or rather paraphonic, which means that the grains play pack at
different pitches simultanously,
depending on the chords you play
but they all play back from the same sample position and have the same
kind of "treatment" like envelope or filtering.
I thought you could maybe do this and some other stuff in the spectral
the idea is to change snippets / loops of existing music into new
music, this idea is not new,
two demo tracks
they are mostly made from a snippet of Nancy Sinatras Fridays Child
