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
