key problem (slicer fx plus tempo change)

is there a way to lock the key while changing the tempo of a track with slicer fx on? it really annoys me that it doesn´t. thanks

The only way I can think of is by recording a loop and copying it to a track deck.

hm...thought about that. but i don´t really use the sample decks and most of my mixes i do on the fly so recording is a no go...but thanks anyways!
