After reading all that is posted here I’m left with a sense of confusion.
My rules – Keep in mind that I do not have KN7000 or a manual, this is right off the top of my head.
Work as the keyboard was designed to work, add your ideas to the system. If you invent a way contrary to the keyboard’s design you will have problems that can not be solved.
1-When saving the keyboard automatically selects that which should be saved – “Performance” -- you can change the preference if there is a good enough reason – only if needed.

2-Whenever you play a sequence from a source other than yourself or your own there is a danger that the sequence may make undesirable changes without you being aware of it.

3-To load to load the 20 custom styles for each endeavor is not a great idea –
so I have four different 20 custom styles that fit special types of music. Big band, Sing-a-longs, Dance and specialty. In an evening I may load the 20 custom styles two or three times. (If needed)

4-I save 10 normal panel settings, “not extended”, for my live playing. Either playing a song from memory or reading I have 10 banks to chose form. Each bank has been created to use with a specific type of music.
EX. Big Band Ballads – Big Bands Moderate – Big Band Strong – Latin – Polka – Waltz –Disco ect—I am ready to play live.

5-In extended play my panel memory, all 13 banks are setup with a song title and a keyboard setup. Press one memory button and I’m playing the song.

My discipline:
1-Whenever I decide to record anything with the keyboard I load my normal panel settings above, this way I am always working from the same base. This includes the sound memory.

2-If I record a sequence I will always copy the style I am using from the custom 20 to the memory style. I feel that no matter what the style is it needs some editing to best fit the song.

3-If I decide to edit a instrument sound I add to the original sound memory, the same sound memory that I load be fore I start anything. My sound memory is always growing in an orderly fashion. I do not have more than one sound memory that would add to much confusion, 40 are enough for me.

4-I do not find it necessary to select certain parts when I am saving unless there is a reason, the SD card has a large enough capacity. When I work with my keyboard I select the first choice of saving which is the “Performance” – Technics knew what they were doing. IMPORTANT, save panel setting to “ALL” I want all 13 banks not three. (Not just A B and C)

5-On my SD card and a floppy I have every area of the user sections covered. Someone can sit at my keyboard and change everything and I am covered.

6-I am very careful with the OTS, I do not like many of the instrument choices. I need to have control.

Scott, I sense your frustration – I am guessing that is because your are going against the design of the keyboard. If I have not covered your issue please respond and I’ll give it anther go.

Hope this helps, John C.
