When I referenced transpose + pitch correction, I was feeding the transpose output into the pitch correction input. Clearly the pitch correction is monophonic at best and the QC cannot do what I want.
With all due respect, I don’t think my expectation that this unit should be able to replicate what a DigiTech HarmonyMan could do back 16 years ago during the Great Financial Crisis of 2008 is “too high”.
Fair point. I feel the same way about the looper; why can my 20-year-old DigiTech Jamman Stereo create loops and allow tap tempo control (allowing speeding up or slowing down of the loop) without pitch change - and no one can seem to do that these days?
In any case, yeah, modern pitch shifting seems to miss the mark just about all the time. As a bass player (mostly, these days) the pitch shifting is good enough for my needs, but I understand your frustration.
I don’t think that the technology to pitch‐correct multiple notes exists yet. The QCs pitch correction is certainly only able to correct one note at a time. Make sure your PC block is placed first.
Polyphonic pitch shifting absolutely exists. There are things that allow you to adjust the speed of loops without changing pitch as well. Sometimes that can be a little glitchy, but the technology exists.
Whether Neural is capable of adding that type of stuff to the QC is unclear. There’s a reason why Headrush licenses the technology for Auto Tune to use in their pedalboard. It wouldn’t make sense for them to build that effect themselves. Developing that stuff from the ground up takes a lot. Line 6 hired people that worked on the Digitech Drop, so it was easier for them to add polyphonic pitch shifting to the Helix.
Thank you. Yes – it is the first in the block, but I’ve given up, and have to just revert to carrying a spare guitar (WHY do singers choose Eb??!!)
You’re talking about pitch shifting, I’m talking about pitch correction. Different function and different purpose. I don’t believe polyphonic pitch correction exists.
It does exist. Just not with Neural
Hey Mick, excuse me if you’ve already explained but what are you wanting to use pitch correction on? If guitar, why?
Really? That’s news to me. I assume it must be a recording plugin. I haven’t read anything about that from Anteres, Molodyne or Waves. Do you know who makes it or what it’s called? I’d imagine the capability to seperate, pitch correct and re-combine multiple voices in real time would be a real resource hog and require more latency than would be tolerable. Who knows? There’s some pretty miraculous stuff being done.
Melodyne does do polyphonic pitch correction, and has advertised the option for quite a while.
Here’s a video from 7 years ago of someone demonstrating it on guitar- https://youtu.be/dv-HNa85YIk?si=1Ebj_WS3OjwW1vRT
Also there’s this plugin- Zynaptiq PITCHMAP Real-Time Polyphonic Pitch Correction Plug-In (Mac / PC)
I stand corrected. There is a plugin made by Zynaptiq
called Pitchmap that claims to be the “first and only” polyphonic pitch correction software. The vids sound pretty awsome. What an incredible time to be a musician.
Oops, you obviously type (and read) faster than I do. 
This seems a bit extreme. I’m the biggest critic of pitch-shifting around. Cliff of FAS hates me because I always used to start threads about how terrible the pitch shifting was until it got better - although it was never good for clean guitar or bass guitar, and still really isn’t. However, that said, In a full-band context, it’s perfectly acceptable.
I think you may be the one person who’s more sensitive to the latency and artifacts of pitch shifting than me! I find the Transpose and Pitch Shifting blocks to be 97% good when playing alone, and easily 100% there when in a full band context. And, not to insult your intelligence, but have you tried using it with band or did you just practice alone with it and determined it wouldn’t work for the band? Because I guarantee you that in a full band context, you’re not going to hear the artifacts, especially if you use any drive or distortion at all.
I assure you I’m not being an apologist for NDSP or telling you you’re crazy, but, again, as the biggest critic of pitch shifting on modern modelers, if something is good enough for me, it ought to be good enough for 99.99999% of others. You may very well be that 0.00001%, but I’d like to help get you over the hump, because lugging multiple guitars sucks. At one point, I switched to Variax which could do pitch shifting or drop D tuning (or both) better than any box, although that may not be the ideal route because you’re more or less stuck with the guitar - and there are NO sexy Variax guitars, unfortunately.
Melodyne works amazing for polyphonic pitch correction.
I recall following and pitching in on some of those conversations on the pitch shifting on the FAS forums back when I had the FM3.
The transpose in the Neural plugins is better than what the FM3 was able to do but it still glitches out depending on what you play and how fast.
The transpose in the QC seems to do the same thing (can’t say if it’s more or equally glitchy) - if I play faster hi-gain rhythm stuff and shift 1 semitone up, it’s very noticeable even with considerable gain and in a band context (and this is with it first block in the chain).
What I noticed, it seems to do a slightly better job when pitching down vs pitching up but yeah - I still notice it enough to bother me & consider it “not quite there” either.
Yep; and I’m sure you remember the chorus of people saying “it’s fine” or “I can’t hear any latency” etc etc. Now I feel like those guys here lol!
Loud & clear lol. Anyway, fingers crossed we get a poly version sometime.
