Tap tempo on Murf.

I just got a MuRF and i find it difficult to sync it up smoothly while playing with a drummer. Now i am using a Roland foot switch ( the FS-5 U) and maybe this is why. Is the FS-1 footswitch more accurate than any other footswitch as far as tempo acuracy goes ? Did anybody encountered the same issue ?

Thxs in advance.

in the case that the murf is the dominant tempo,the drummer should play to you.
