Tim,

Sorry, but am reading SZ only now and all the turbulence about the SD card.
1/ As mentioned by Scott any card must be formatted on the PA500 itself
2/ Any simple and preferably older SD card will do.
3/ Any card should be 2Gb max.

Don't understand why anyone would want to use a 4 or 8Gb anyway.
You need literally hundreds of thousands of styles , performances and sounds to fill up 1Gb !!! Only if you would include masses of midifiles you would run into problems with one 2Gb card............................

Keep us posted !!

regards,
John
