MPC Key 61 Undo button and arpeggiator info

Hi, does Undo button on MPC Key 61 (if Key 61 is used in controller mode) also work when using Cubase as DAW? If yes, does it erase the last sequence layer or the whole sequence if overdubbing? Also, does arpeggiator function on Key 61 only work if Key 61 is used standalone or also in controller mode (MIDI data of arpeggiator is send over USB to the Cubase? If the latter, I can record the arpeggiator data in Cubase track right? And the arpeggiator tempo is synced with Cubase automatically too? Thanks!

Also, please let me know if pressing Undo button on MPC Key 61 in standalone mode to erase last sequence layer, does it work immediately with just one Undo press or I have to press once again to confirm the action?
