In SX 3 all was OK.
Since 4.0 and in 6.0.3 I still get this annoying bug with Pitch Shift (In envelope mode).
make a pattern of one shot samples (1/8 or 1/16, nevermind).
Then go to Pitch shift, set Range to 12 or 16 (nevermind).
MPEX4 preset - any mpex (solo/poly musical or any other).
Make a pitch envelope. Process.
You will see all one shot samples in the end are out of grid!
I mean MPEX algo on PC (dont test it on MAC) works buggy in envelope mode!
I’m not sure if this is a bug.
I would rather assume that this is a behavior of the mpex algo and that one does not have exact congruence of the transients and offsets regarding the original and the pitched material.
