Help in choosing a rhythm "box" Help. Need some advice re attaching a backing machine to my keyboard. I have a Technics KN 5000 keyboard and have purchased a Boss JS-5 Backing machine. The Boss has some great dance sounds. I midid the two together and the keyboard controls the JS-5 as far as Stop/start, tempo etc .Unfortunately when I play the keyboard and change chord the JS-5 does not and continues to play its own chords. Is it possible to set up the Boss to change chord with the keyboard or not. If not the JS-5 is only good for the drum machine backing. If I have bought the wrong machine is there one on the market that will give good dance sounds and be compatible with the keyboard chords. You will gather that I only play for pleasure and not very well Any advice would be most appreciated
