OK - found a few answers, and a few still evade me.

#1 - Fran, you'll like this - if you load a song file (smf or audio) and start play, you can then go to the next one to be played and select it .... now if you need to cut the 1st one short, for some reason - you push the transport stop button (sync/start), and THEN the start/stop to begin the next song instantly. The buttons are right on top of each other - rather handy, although in most cases, you'll wait till the song is over and then the new song will load instantly.

#2 - It's a dream to have a style library so vast in one place ... OMG - you put things in folders, and they;re there for you when you need inspiration!

#3 - the song player works great, if you're not in a big rush. Your only access cursor is the data wheel, but there's an ipod-like "fast scroll" if you hold down a button. Works fine going from midi to audio in real time.

Now, the still puzzling things:

#1 - won't remember the new "default" or start up patch that I write. Also forgets expression settings and sometimes tempo settings (I like AUTO).

#2 - This MAY be a computer thing .... there are "ghost files" loaded on the usb stick that have a dot and underscore before the title, and these do not play. All the originals are in the same list, but you need to scroll past these "dead files" first. This may be a windows/Mac incompatibility ... I'm still checking on it.

#3 - I admit, I'm spoiled by the ease and quality of the Korg MP3 recorder, and I only tried this one twice, but both times - it was awful. The recording skipped and hiccuped during playback, just seconds after making the recording.
