Hi i'm Ash, im 40 from North wales. I'm learning to play my Yamaha E453 keyboard by playing to midi files but i feel as though im not playing, the midi file is doing it all. I have limited movement, i can only use my left arm (not fully). I'm a big Queen fan so i want to learn Queen songs on midi files. What should i play along with the file. I play the melody but once the melody stops and the guitar solo plays what do i do? I'm no good at improvising.
