Thanks for extra info UncleDave, I have managed to store my two MF's OK, they only amount to about 140kb, I have read in the manual that there is 1MB storage space but I would expect a lot of that is aready taken with other applications.
Will be using the PSR2000 for the first time on Saturday night at a hotel based Masonic Dinner-Dance in Bournmouth UK(dont know whether you have those sort of functions in the US)these gigs are long and tedious! arrive at 17.30 set up by 18.30 disappear until 22.15 play until 1am long drive home, in bed at about 4am, sleep all day Sunday.
Look out for report on how the 2000 performed on the gig sometime Sunday(thats if I get up)
