Simple Pitch Shifter

[Hierchiss]

I've been looking at a lot of pitch shifting schematics today, and honestly haven't really gotten very far. I'm looking for something super simple to start off with. If you could help me out that would be greatly appreciated!

Have you yet stumbled on the schematics archive here?

Welcome to the green board!

Octave(s) down is somewhat easy thanks to dividing logic chips, but the frequency tracking can be bad.  Octave up is also possible, normally by rectification and some smoothing.  But, generally, pitch-shifting is hard to do without some digital signal processing.  If you're just looking for a pitch shifting effect in the context of noise, I'd recommend a ring modulator, of which there are also designs in the archives.  And also, welcome!

thank you!

in your opinion, which one from the archives would you think is the easiest to start off with?

Probably the octavia (for octave up fuzz), the "Voice Changer" (for general noise pitch shifting) or the polyfusion octave divider (for octave down(s)).
