HELP Please - Zoom G3X Looper and Drum Machine Out of Sync

[GV]

Hi,
I have a Zoom G3X and am finding that the looper works as it should when I do not use the drum machine, but when I try to use the two together, the looper does the following:

1. Starts to record several seconds after I have stomped on the 'record' switch, and
2. Is out of sync with the drums (probably because it is starting to record later than I am 'telling' it to)

I have read that some other people have had this experience with the G3 and the G3X, and that other G3 and G3X owners never experience this.

One person wrote somewhere that he temporarily fixed this problem by restoring his G3 to its factory default settings, but that several hours later, the unit again put the looped recording and the drums out of sync.

Does anyone have a solution to this problem?

Many thanks.
