Derek, you said that you copied the internal style to the Composer. That should work, but I suspect you may have copied to memory A and are trying to play from B or C, or even possibly an internal style. Sometimes it works best to copy the style to all three Composer memory locations (so that you don't accidently use the wrong one) and be sure to use the "ALL" selection as Roger said. Then be sure to use the Composer rather than a built in style. I routinely use KN7000 styles with the KN2600.
