Hi Larry:
The intent of the "TIP" is targeting the pre-built rhythm pattern only. I'm not familar what the KN rhythm patterns have, so I'll just use an example.
Lets say you record using a KN6000 pre-built rhythm Foxtrot, keeping the pre-built location. You use panel memory to store it, and record your song. What is saved in panel memory is the location and where foxtrot resides. Not the actual beat.
Now take that recording and load it in a KN7000, you are not going to get that exact Foxtrot that was on the KN6000. You will get the KN7000 Foxtrot, it maybe slightly different, completing different or in some cases the same(there have been repeated patterns).
If you like a rat-a-tat-tat and want to keep it, you must copy it to the composer. If not, the different model may have dat-o-dat-toot.
Hope this helps explain it.
Anthony
