Broomstick Bass unable to sync to drum vst

I’ve been looking for an auto bass accompaniment for GP and there is just nothing to be found. I dug up Broomstick Bass that I have owned for a while and it still does the job after being converted to 64bi using jBridge. It follows my guitar chords pretty good and seems to run ok. However, Broomstick Bass doesn’t have a midi sync button and I was wondering if there was any way to force B.B. to sync to GP and therefore the drum vst. Is this possible please?
