midi is the electronic equivalent of sheet music, or the song roll on a 
player piano.   its just codes for notes and timings, its not the audio.

do note, if this is a stage grade electric piano, using big phone plugs, 
the audio level out is not quite the same as consumer line level that a 
computer input would want to record, you'll likely have to crank the 
recording level way up, increasing the noise floor of the recordings.   
the cure for this is something called a 'DI box' (Direct Input), or 
using an amplifier or mixer that has a consumer line (1V P-P) output.    
an alternative might be to use the headphone output of the synth, with 
it set to moderately loud volume levels (say, 6-7 on a 0-10 scale)
