After a thorough test in Reaper I can say: This one
works perfectly well - a true "revival"

Interesting plug. Just had a play with the "old" version which I had from
way back & forgotten on a track I am doing that needed some Baritone-y
guitar & tweaking regular guitar part down actually sounded almost as
good as my real bari!
I used the old version for vocals-transpositions of one whole octave (!),
and it worked good in many situations.
Just to remember:
For natural fine-tuning of audio, especially vocals,
Autotune, Melodyne, VariAudio (Cubase), Time Machine
(Apple) or even ReaTune are the best tools.
But for a pitch transpose of a whole octave it is not
easy. Here the only way is to try many different plugins,
including Autotune, Melodyne and all those.
In some cases, for some vocals, Kerovee or Nix shifter
reveal better results. If you want a whole octave you've
to test a lot - and maybe you've luck - or sometimes
it's impossible. But ... the chances are good that you
may succeed with the new revived "Shiftah".
And here we've to thank the author of "Shiftah":
Thank you Nick (nix808), this is a fantastic thing (and
you nearly forgot it - unbelievable!) in a happy new
64-bit cleaned up version. Probably your best plugin ever.
