the point of a large card is audio, I have 150 karaoke compact disk audio tracks on a 512 card to play along with a real orchestra. With 999 audio tracks available on an SD card requiring somewhere over 3GB space, 1G is obviously not enough for the max possible potential of audio play.

The 99x20 Technics file load is equivalent to 19,800 songs at 10 to a sequencer, in addition to 5,940 composer style loads, or alternatively in addition to 39,600 custom style loads, but is still not the whole story since add in midi files and a card can hold 20,799 songs, and you could fill the single custom folder to increase the potential custom swap by many hundreds of styles, let alone fill the imexport folder with midis and swap midi files from the pool on one card to increase the 999 potentially playable. For Technics and midi only you would probably only need a 256 for around maximum use.

Roger, everything in memory can be saved whether custom or composer and therefore restored after loading something else. If a custom style could not be restored then it was just saved incorrectly before the new custom was loaded.

Bill, my experience on save is the opposite, a performance save from initial takes longer on a 90% full 8MB card than it does on a 60% full 256MB card, albeit a mini-sd in adaptor, so it depends on the card.
