i have a yamaha psr 1100.it has little internal memory.can I use something for external memory for example something in the midi ports which can used for external memory. The floppy diskettes are good but there are very slow for realtime performance.or can I remove the floppy drine and put sd memory card drive like the newest models of Yamaha???? I have some nice styles and I cant use them as I like!!. Do you know where can I find good greek styles????? thanks
