Hi Chaochi,

Once you have the signal in, there are many ways to adjust it's
character.  You can filter it like any other signal using filters
(i.e. butterlp, butterbp, moogvcf, etc.) for coloring, or phase vocode
it with another signal to get a different coloring, or convolve the
signal with an impule response, etc. It all depends really on what
kind of character of sound you are looking for.

As for tune, are you trying to tune a signal say like Antares
Auto-Tune where the signal becomes quantized to a scale?  Or shifting
signal's pitch via a fixed amount (i.e. transposed up a minor second)?
