Fractal Fx8 - pitch shift not accurate

[Bash_Man]

So I am using my FX8 as a whammy to pitch 2 octaves up. I've got everything setup correctly in the scene settings and the expression pedal is calibrated to go from 0 to 100 from toe up to toe down. However, I noticed that my 2-octaves up does not go that high.

So for example, if I play a part where the riff starts on the 15th fret of the low e, I'd have to start on the 16th fret of the low e for it to "pitch" accurately.

Any suggestions as to what I can check to correct that?

Thanks

Like any of the other fractal units, it has to be some type of pedal calibration thing. Are you sure your expression pedal is functioning correctly? Man...I haven't seen an FX8 for like 5 years.

Thanks PB. Last I checked, the pedal calibration shows 0 to 100 when rocking toe up to toe down.

Very strange, Bud. Did you try a different TRS cable?

Not familiar with the FX8, but is it possible that it's an intonation issue with the guitar you're using?

I did and same result. I tried everything possible that I could think of before posting.

I checked the low E harmonics on 12th fret and fretting the 12th fret and it's pretty spot on.

Does the FX8 show its processing limits maxed?

as in CPU or something else? CPU right now is at 74%.

Bingo. You’re likely over utilizing the CPU. Try disabling everything but the 2 octave effect and see if it improves. If so, you need more power.

Interesting! I realized I had a Reverb block in there that was eating up about 20% of the CPU and not being used. I deleted that, and I'll test it out.

Is one octave up still flat?

This thread made me go a bit down the rabbit hole. Too much to back and forth in a post, but assuming you've followed some of the settings advice here?

Yep. Latest official release from fractal.

Actually no. I took the same preset and changed it to 1 octave and it goes up 1 octave no issues.

Thoughts ?
