Personally, I always copy a style into the composer and work on it there. While Gunnar uses expand mode when saving the style, I don't do that unless I'm using the sequencer and moving from variation to variation with the panel memory buttons via the foor switch. When just dressing up a style or getting them ready for future recording, normal mode is my choice. That way, tempo and variation settings remain constant while changing from one pm to another. Sound levels or balances can be set in with the instrument of choice with each pm setting, including special "voices" which should be saved in sound memory, like Gunnar states. You cannot save sounds into memory from expansion boards and have them reproduce exactly on a keyboard that does not have the expansion board. I found out the hard way while recording a kn6000 song from a kn6500 to a cd recorder - garbled sound! I had to stop in the middle of the recording, go home and sequence the song with another instrument. What a bummer. I thought if I included the sound into sound memory, it would reproduce okay, but the School of Hard Knocks sent me to summer school and I learned the proper way. I still think that if an instrument is included in sound memory then when the style is loaded, sound memory would have all the necessary information to reproduce that particular sound. However............! Alec told us a long time ago to experiment with features you're not really familiar with because you won't hurt the keyboard, but most players shy away from that way of learning for one reason or another. It's easier to play along and do what you are familiar with, I suppose, but somewhere along the line you'll hit a learning plateau. Then one has to hit the books, take lessons or end up snagged at that level while others pass you by. I learned that lesson on the guitar. Without professional guidance I would never get beyond mediocre, so I gave it up and took up organs and keyboards. I still haven't had lessons, but I practice a lot more. What's that old saying about an old dog and new tricks?
