J.Larry, As far as I can determine, the modification procedure of the EQ settings in the KN7000 is essentially the same as in the KN6xxx instruments. It has to be done in the composer, as you suggest and then the new style saved to Disc, SD or whatever. I tried it and it does work. I can't find any other way of altering EQ on individual parts of the Auto Accompaniment.
Bob, The SD card filing system has 99 Folders, each folder holding 20 files. Both Folder and File names can be up to 16 Characters long. The 99 / 20 system is irrespective of card capacity, as far as I can determine. So, if all your 'Saves' to SD card are arranged to only save the required data, then it is possible that you will be able to use most, if not all of the folder and file slots, within the capacity of the supplied 8Mb card (1980 files). If however, you are saving large amounts of data, say custom styles and sequencer, then the files will be considerably larger and the 8Mb capacity will be filled up, before you reach the 1980 file limit. In this case, a larger capacity card would be required.

I've been having a look at the KN7000 SD card filing system and made the following observations.
The 8 Megabyte card supplied with the KN7000, when blank, reports in the SD menu as having 6608Kb (6.608Mb) free. 8Mb = 8192Kb : 8192 minus 6608 = 1584Kb So, where has just over 1.5Mb of memory gone? I then tried the same operation with a 32Mb card (32768Kb) and it reports only 30352Kb (30.352Mb) free! This time, Missing 2416Kb. So where has just over 2.4Mb of memory gone?
I then tried some comparative tests saving identical data to the 8Mb SD card and then to Floppy Disc. I named the first Folder using 16 Characters and this reduced the free memory from 6608Kb to 6576Kb - a drop of 32Kb! The SD card file data was deleted between tests, so all tests started from the '6576KB Free' point.
Test 1 : Save 3Bank Panel Mem, Current Panel and Effects only, naming the file group using 16 Characters for SD. Results : Free memory now 6504Kb - Operation used 72Kb. Same file arrangement saved to Floppy used 17Kb.
Test 2 : Save 'Perform' option again using 16 Character file group name for the SD card. Results : Free memory now 6400Kb - Operation used 208Kb. Same file arrangement saved to Floppy used 95Kb.
Test 3 : Save all Custom Styles only again using 16 Character file group name for the SD card. Results : Free memory now 6520Kb - Operation used 88Kb. Same arrangement saved to Floppy used 205Kb
Test 4 : Save 'Perform' and Custom again using 16 Character file group name for the SD card. Results : Free memory now 6392Kb - Operation used 216Kb. Same arrangement saved to Floppy used 429Kb
Test 5 : Save 3Bank Panel Mem, Current Panel and Effects only, same data to 10 file groups, each 16 Character name. Results : Free memory now 6216Kb - Operation used 360Kb. Same arrangement saved to Floppy used 171Kb. This means that the average space used on the SD card for each operation was 36Kb compared to 17Kb on Floppy.
Interesting stuff Eh??? The strange result is the large difference when saving Custom Memory. This operation shows a considerable reduction in the required SD memory, compared to that on a floppy disc. All the other operations required more SD memory than floppy space. I repeated Test 3 several times and got the same result every time.
Finally, I continuously transferred data to the 8Mb SD card, from floppy discs until it reported full. Toward the end of the process, I transferred only small files so that I didn't overflow the capacity and get a erroneous result. Having filled the SD card, I then took the floppy discs which I used, and added up the files sizes, using Windows Explorer. The total file size was 6.32Mb.

interesting, but I would not use the 7k display as comparison. various points:
I assume the cards format as FAT16 whereas floppies are FAT12, so differences between numbers of small and large files may build up?
Cards are specified as MB = 1,000,000,bytes like every similar medium like hard drives, whereas windows and ide channels count a MB as 1024*1024 = 1,048,576 bytes so an apparent reduction in size always takes place due to this with every medium.
The filesystem must have an overhead, if this is relatively constant, it will be advantageous to the bigger cards and disadvantageous to the smaller.
We shall see how filling the filesystem with playlists etc affect the capacity, or whether this is already spoken for in the overhead.
5448 kbytes free on the 7k shows as 5579 kbytes in windows. If you look at the exactly the same files on pc and floppy you will see a different number of bytes used due to above reasons.
It looks like the file system overhead is the majority influence.
