Pitch command +sample offset versus chromatic input+offset

Track 4 at the left shows pitch shifting with normal keyboard tranposition + sample offset
The right track uses the pitch up command +sample offset
The results sound totally different .
Anyone knows why ?

because Uxx and Dxx start from the specified note pitch and bend the specified amount over the course of the line

Ahh yeah , makes sense but since I always work on a rather fast LPB the transposition bending from initial pitch to destination pitch ( U,D command ) wasn’t always clear .
It’s indeed very clear when using a low LPB
