hi the 4000 series was a top end studio designed keyboard which you could put programmed disks into it, you can still get the disks for them with lots of pre prog sounds on it or you could programm your own onto.. when they came out i dont know for sure i have had mine for about 2 years ,, i was thinking of becomeing one of those bedroom musions , however im crap at makeing music and it was a short lived hobby..if you go to google and type in psr 4000 hamaha keyboard you will find lots of info..
