The combination can, I dont think freqtweak can cross
channels, but you
can feed through FT (in 4 channels) then tapiir. Infact I do :)
So you run multiple instances of tapiir?
It would be nice if tapiir would be a bit more flexible, with the number
of input/output channels and the number delay lines configurable, and
the gui generated accordingly. I'll keep it in mind...
