Wow, I heard of "fftease" before, but I had never actually looked
carefully at it. That looks incredibly promising, thanks so much!
I should probably start to look seriously at VASP too - I'm really
starting to get more interested in PD for non-realtime sound design
anyway, as opposed to a realtime tweaking environment.
