Do you want to convert WMA to MIDI or WMA to MIDI?
Try this: http://midconverter.com/midi-to-wma.shtml
I have A Keyboard piano and on it I can put songs onto the internal Memeroy but they have to be MID ( or MIDI) files. Does anyone know of Free converter that Would do a good job and easy to use? I looked at Nero 7 but did not find anything that looks like it'll work.
