I play in a guitar duo where I play lead, and my partner plays rhythm guitar. It can be surprisingly difficult to get the beat just right. What we do is when learning a new piece, we start off playing with a metronome, or set a suitable beat going on the KN7000, until we are reasonably comfortable with the tempo. Then we turn off the metronome (or keyboard) and try to maintain the same beat on our own. This approach works very well for us.
