UNABLE TO SYNC MPC4000 TO MTC?

Dear fellow MPC4K-users,

when I try to sync my MPC4K to external MidiTimeCode, coming from my DAW (NUENDO) I can see my 4k jumping around to the various locate-positions, but it doesn't start at the given time……

At the "Sync In" page, I

Turned on Mode: Midi Time Code
Switched frame rate to 25fps
Prorammed Sequence Start Time: 00h 00m 10s 00f 00sf
Switched on function-key F2: SYNC: ON

When I start my DAW (at t.c. 00h 00m 00s 00f 00sf), the 4k doesn't start playing the sequence at the programmed start-time……..

Any help welcome!
Thanks!

I figured it out:
it seemed to be some mis-setting in my usb>midi-interface; when I switched the preset all of a sudden it worked.....

Thanks anyway for your attention!
