It occurred to me that it may be useful to list the Components of a KN Song File (a TFLDxxx file) and their purpose.
The number of Components in any Song File is determined during the original Save operation.

cmp - Composer, 3 banks of 4 variations, 4 intros, 4 endings and 8 fills each. 8 Part - 2 Drum parts, Bass and Accompaniments 1 to 5.
efc - Effect Memory file with 50 DSPs.
lsw - Current Panel memory.
msp - Performance Pad files. 18 pads, 3 banks of 6 each, pads 2 track.
pmt - Panel Memory file of 13 banks of 8 memories each.
sqt - Sequencer file, 10 songs and setups.
tm - Sound Memory, 40 sounds and drum kit.
ast - Custom Style section in flash memory. 20 complete styles, each style with 20 composer patterns, 4 registrations , 6 performance pads, and any edited sounds, drums and effects.
fav - 4 Favorites Pages of individually programmable menu functions in flash memory.
hmp - The individually programmable Home Page in flash memory.
md - 3 User Midi setups in flash memory.
cst - A single Custom Style in flash memory. 20 composer patterns, 4 registrations, 6 pads etc.

EDIT : Forgot to mention in my previous post, re. copying files from Floppy disk to SD Card.... Instead of doing so one at a time by loading from floppy and then saving to SD Card, there is a facility on the KN7000 to copy all the files on a floppy disk directly to an SD Card Folder in one operation. Press SD LOAD > SD TOOLS > COPY FROM DISK. It's a very slow process limited by the speed of floppy operation.
