Hello,
Attached is a patch with a fixed-interval time domain octave harmonizer (octave down and up). The approach differs from regular time domain pitch shifting, and the result is also quite different. A delay is noticeable for the octave tones, but the harmonies are very smooth. No rough tones, as they are normally associated with time domain pitch shifters. It is therefore particularly suitable for long notes.
