The second way is to have all the key you want as part of the wave in two groups. (Let me re-iterate; thats all the keys you want lit up in identical groups. eg; 'All' and 'All2') You have one with a wave to the right at the start, then the second groups effect should start over halfway down the lighting editor (if that made sense). You then have to play around with timing to get them to line up properly.
