Hello. I play violin and use MIDI files found on my computer (via Windows 7) as back-up music for gigs. These MIDIs are saved to a 3/1/2" floppy disk which is what my Casio WK1800 can accommodate after formatting them in order to play in the keyboard. Because I am unable to carry around my 40lb keyboard to gigs, I want to transition my MIDI files over to a reliable laptop computer that has ports for speakers and will be able to play my MIDI files continuously when playing a gig. I am searching for a laptop with speed, large memory capacity, Windows 7 or Windows 10 capable. I have contacted various music stores in my area but get a different answer each time. I realize that my Casio WK1800 is obsolete and not too may musicians are familiar with this process I am trying to accomplish. Thanks in advance for any help you can provide. Annmarie
