Has anyone used the metronome of the H2 Zoom recorder in playback mode?

I figured using the metronome to record one part of a duet and then playing the other part using the same setting would make everything simple, but the recording with the metronome beat overlaid shows I'm always about half a beat off. (I don't have rhythm problems when I play with my teacher.)

When I tried simply playing staccato g's in time with the metronome clicks, it was even clearer - it sounds syncopated. I also tried tapping in time with the clicks (in case my tonguing is slow and I'm compensating when tapping with my foot): same thing.

Any ideas, except for counting the clicks as "and"?
