Don/Gary,

Thanks for your explanations, but I still do not get want I would want really. I can NOT replace all five instrument tracks by a piano or electric piano, just try and do that for example with style Rock&Roll ( R/B , page one , style 9).
Two of the tracks, when replace by piano play a high pitched arpeggio ( obviously a few octaves too high). YOu will encounter this with many more styles. Scott's explanation is plausible but still I think one meets with a limitation not found on the Korgs..............may be wrong..............

regards,
JOhn
