building harmonizer for my electric guitar

March 8, 2007 | 11:26 pm

Hi, everyone!

I’m trying to build a good-quality harmonizer with no latency. I’ve already tried using the gizmo, freqshift, fbinshift and hilbert objects but had some latency problems. I tried changing the windowsize and it helps to get a fast response from the fft but I do lose a lot of sound quality.

I also worked with very very short delay lines but I still don’t seem to get close to what commercial harmonizers for electric guitar (like the Eventide-3000) can do.

Does anybody have some info that could help me develop a nice and instantaneous harmonizer?

Hi, Mustafa.
A harmonizer doubles the notes you play in real time at any given interval. Say you play an A on the guitar and you want it doubled up a perfect fifth… the harmonizer "plays" that perfect fifth (E) each time you hit a note on the guitar.
