Virtual Capo issue

Setting the 'Detector Source' to 'Block In' seems to help a little bit.

This, I believe, is part placebo part some random deviation which can indeed sometimes make things better or worse. Changing this setting (or something else) may remove the problem today but it may reappear tomorrow.

VC performance is inconsistent and depends on who knows what, maybe moon phase.

New recording so that I could also capture a DI. Preset attached (scene 2).

VC test (no pitch shift, notes, chords, pitch tracking off):

Dropbox isn't ideal as it discloses personal email when downloading content (zipped attachment of a very brief DI is better imo). Anyway re-amping your DI here as best I could from the dropbox playback without signing in I get the following using your preset on my Axe3 mk1 at Fw31.01 modded for (scene1=no pitch, 2=Notes, 3=Chords, 4=Off - Modded Preset Attached). Pretty much what you got suggesting nothing amiss with your particular unit or globals - I get similar attempting with my Epi335- tracking on mine is a bit different (maybe due to poor playing 🤣 ) so maybe guitar used makes a difference to how VC performs. NoTracking seems to work best to my ear, but I don't really know the controls very well so...

Maybe it has something to do with the specific guitars
Is it a Floyd vs Hardtail
Perhaps something like a guitar with an evertune bridge will do better than a floating trem system
I am just guessing here

Ya, could be - what's interesting too is that it sounds better live to my ear than listing back to it recorded. Either way, if you listen close - it wobbles - fine for basement hackers like me, but maybe not for others...

I’m not sure what this understanding is based on.

I, for example, expect it to not have the unpleasant oscillation/“warble”. Even if the whole thing reverted to an older algorithm from a few firmwares ago that didn’t exhibit this issue, I’d be quite happy.

Every product on the planet that offers this type of pitch shifting has this unpleasant oscillation/“warble”. The current firmware seems to have less than I have experienced on this unit. If it was an easy fix, it would probably already be fixed. Just my two cents. I will keep it to myself from here on out. Carry on.

Not true. Digitech Drop or the Boss XS1 or EHX pitch fork for example don’t have that warble. It’s not normal. Like I said it should be plug and play and not depending so much on all kinds of settings or specific guitar. Either something is wrong on the users side or it’s a bug in the algorithm.
 
What guitar pick are you using?

Thicker, harder(😏) picks can produce chirp which VC may try to transpose that transient and give you warble before locking onto the actual note.

This has nothing to do with picks used. I get it with some chords and not others, also it behaves differently on different days. With the same pick. Also the warble is prominent during sustain.

Just for clarity do you have a free floating trem and do you rest your hand on the bridge
IMO trem systems can call all sorts of tuning stability issues even something like a Wolfgang D tuna

I’m getting so many warbles and artifacts. Is this what should be expected?

By the way, did you also try other drop tune or pitch shifter pedals and did you have the same problems with them?
Same question for vangrieg.
 
I spent some time on the Pitch Shifter today. Even before the improvements it was better than "Brand N" (which I've been told is the greatest pitch shifter in history).

Here's a comparison of "Brand N" followed by the Virtual Capo with the improvements from today:

https://www.fractalaudio.com/tmp/ps_comp.mp3

It's not perfect and it never will be. It's impossible to do real-time pitch shifting perfectly. It's a trade-off between latency, transient duplication, tremolo effect and CPU load. I find transient duplication the most objectionable so our shifting leans toward minimizing that. Transient duplication makes things sound like they're in a tunnel due to, well, duplication of transients, which causes comb filtering.

If we had unlimited CPU resources it could probably be better but we have to balance CPU usage with customer expectations. If the Pitch block used 50% CPU customers would complain (well, they complain about everything already but they'd complain even louder).

Very nice. Definitely a HUGE difference between the two in the clip. The one that starts at 0:23 aka Fractal? Sounds sooo much better!
 
It would be awesome if there was a Fractal pitch shifting unit, just monster processing power dedicated to nothing but pitch shifting, but with the DSP expertise of Cliff and the deep mod options of Fractal products. I would imagine that would best of all worlds.

Or, in the next generation units, to design the flagship with processors dedicated to nothing but pitch shifting.

Thanks. Which actual one is “Brand N”?
It really sounds bad, but would be good to know what you are comparing to exactly.

And how do you explain the (extreme) warble that many/some Fractal users apparently are experiencing? (Like in the OP’s clip)
