Does anyone know of an all-in-one standalone mixer with tempo-locked pitch shifting?

I need tempo-locked pitch shifting, not pitch-locked tempo change.

I need this because i do A LOT of harmonic mixing, and nothing i have found does this.

Plz halp.

You can do this as a mapping within traktor, and I believe I saw something recently that could enable this sort of functionality...I'll have to dig around a bit.

EDIT: you could get pretty wild with an F1 mapping where the key adjustment knob was controlled smoothly with the 4 faders for each deck, and then map musical interval changes in semitones to the pads.
