To use the SD card on a PC you need a device to plug it into - a reader/writer device that hangs off the USB I believe is available. I lucked out, the Toshiba Satellite 6100 laptop I use has an SD slot built in, just push the card in a a new Drice E: appears. That should work for SD-Audio files but the management of Technics files requires keeping a map file up to date which I am trying to reverse engineer. There is a 16 bit number after each file name mapping that seems to be a set of flags indicating what parts are available to load for that particular song - panel memory, sequencer etc. This may take a while to decipher using trial by error since it is not documented.

Like you I feel the manual isn't a full meal deal - I upgraded from a 1400 to a 7000 and was very surprised to see the manual was no thicker than the one for the 1400 - but all those new features have to be described somewhere don't they, hmmm. Most of the information really is there, it is just hard to understand the way it is written as a set of isolated factoids. There is very little overview material to act as training on the instrument and to bind all these little factoids together into something that gives the big picture IMHO. For example I want to sit down and write a 16 track composition by playing the parts in the sequencer a part at a time - how do I do that? A retorical question I don't expect an answer to but an example of what I see as the major short coming in the docs shipped.
