As you can see above the transpose maxes out at 11 semitones with mpex.
This has always been 16 semitones.
I regularly use this algorithm and i cannot pitch to an octave.
When can we get a fix for this? It has been broken for roughly 2 years now.
If one disables time correction then no algorithm needs to be used. Then it’s just resampling.
Do you remember which version of Cubase offered a bigger range for this algorithm? I have a two year old Cubase and it is the same +/-11 as on your screenshot. With which version was it different?
Hey Johnny, where’s your humor? 
My answer is the ss from the manual with the limitations 
cheers
*edit: I opened 12 now and I can confirm 11 semitones as op.
In Cubase 11 it was possible to pitch shift by 16 semitones using the MPEX algorithm. As of Cubase 12, Steinberg has reduced the maximum interval for some reason. Here’s an old thread about this topic:

it’s a bug, you don’t just reduce a feature to not hit a musical octave, that would be nothing short of stupid, it’s an error thats been overlooked surely.
Can we get any information on when this bug is going to be fixed?
@almaelectronix You are posting a screenshot about limitations on non elastique algorithms, however, this same text statement is also present in the cubase 11 manual.
And cubase 11 with mpex pitches to 16semitones, like it always has since i first started using cubase many years ago with cubase SX3.
This is sudden and abrupt bug that has broken workflows.
Appreciate you trying to help, but you are wrong on this one.
I would say probably never!
cheers
Further proof of the bug.
You can’t even pitch up or down 12semitones in envelope mode, with or without any timestretch.
MPEX code is owned by Zynaptiq, so I’m not sure who’s responsible for the 11 semitone limitation here. Steinberg just licenses the code to include in both Nuendo and Cubase but I don’t know what, if any, wrapper they put around it.
Nonetheless, it’s pretty clear that Zynaptiq is not going to update MPEX to support Mac native silicon so I can’t imagine it has a long term future with Steinberg offerings. I suspect @almaelectronix’s prediction may be correct.
With my latest post i just showed that this bug exists in envelope pitching without any timestretch algorithm used, so this is obviously a steinberg bug & nothing to do with mpex.
