Anyone built an Autotune in rack? Think I’m going to give it a go. Love to discuss. Cheers
do you mean combine existing modules to make an “autotune” patch?

Yes
I use a fair bit of autotune for creative purposes in Logic. Thought it would be fun to make something in rack that can be a bit more personalised and creative.
Are there enough pitch aware modules in VCV to do that? That sounds like a cool idea.
Hmm, I like to make my own effects from scratch, but fairly simple stuff like phasers with all-pass filters and chorus/flanger using delays. Autotune would be a tough one! I would start with this module, I was surprised how good this sounds with live guitar and it tracks really well:

I gave this an attempt and discovered a way to turn an otherwise decent performance into what sounds like a choir of 4th-grade horse girls singing with their mouths full of oatmeal. (Once I remembered to turn the mix knob on the pitch shifter to 100% things got somewhat better.) T-Pain, eat your heart out.
Ok, so first I used voxglitch autobreak to play some random vocal loops. I used bogaudio rgate to easily adjust the clock so autobreak plays the sample at a reasonable tempo.
Ran the audio into a pitch-to-cv module. (Got better results running it through a bandpass filter first.) I tried nysthi’s C2V module and Entrian’s Follower module, liked C2V better but ymmv.
Took the cv output from the pitch-to-cv module and ran that through a quantizer. Then I ran that into the A input of an alef’s bits math, and the original unquantized cv into the B input. Took the minus output and ran that into nysthi’s stkpitchshifter module’s percent input, and ran the original audio from the autobreak through the stkpitchshifter to the mixer and with a little reverb, it sounded not too bad. You have to adjust the smoothing unless you want the T-Pain effect and this method really doesn’t do well with fast parts, harmonized parts, or instrumental music but it still seems like it will come in handy to wrangle a loop from one key to another.
EDIT: I’m not a math wiz so hopefully someone able to think more clearly in the math department will chime in with the final say here as to what the correct formula would be. I doubt that I got the formula right. It wouldn’t be something as simple as quantized minus original.

Cant wait to check this out! Thanks for pointing me in this direction.
This is super cool and I cant wait to build it myself! and yes, im looking for T-Pain FX (for lack of better term) - but added hecticness. T-Pain on Acid FX! For now I have a day job to plow threw but thank you for the example. Really looking forward to trying to put it together. Thank you for the contribution. I’ll reply to you post with my attempt in a couple of days!!! pumped
Cool! And no, nothing wrong with those maths. The difference between the actual pitch and the quantized one is the same as the amount of correction we want to do, so indeed correction = quantized - original.

This is a fascinating project! For a more refined autotune effect, you might consider experimenting with pitch correction modules and fine-tuning the quantization to better match the input pitch. Also, integrating a smooth glide or interpolation between pitches could help achieve a more natural sound, especially if you’re aiming for that T-Pain effect with a twist. Looking forward to hearing how your build turns out!

Thanks for the Input @jhoney12. I raised the topic but still haven’t got to building anything yet. Taking on too many projects again. Hopefully have somthing to share soon.

Messing around with this Module you suggested. I definitely didn’t make an autotune patch but I definitely made a cool creative Vocoder thing.

I gave your patch a build, it’s is a great start! Very logically put together. Pretty sure I wouldn’t have been able to put this chain together without you help. Thank you so much! I’m going to get to building on it, looking forward to seeing what comes from it! I’ll post what I come up with. For real, thanks again!
This project is looking really cool
