The Repeater works well in this setup. You can either tap the tempo as you = play, and the Repeater will speed up or slow down accordingly, or you can (= if I remember correctly) even have it sync to an acoustic bass drum track. = I never did that with the Repeater, but with a Quasimidi Sirius sending mid= i clock to a Repeater. Other possibilties: 1. Make sure somebody who is able to dominate the tempo (normally, a loud d= rummer) can hear your loop very clearly. At best, very loud in his inears. = I also played with a drummer who was very happy to look at the flashing tap= tempo light of my KP2 synced to the Repeater. 2. Use loops which work well with tempo changes. 3. Learn to play very tight.
