It should be nice to have EMC style converter Pro,it has a function to make styles from midi,but you should try Cakewalk, put midi in, check the tune, transpose everything in C-(that´s absolete necesary) then get only the parts you need,like Intro 2 bars or Basic " bars, you can even "loop" them in sequencer to listen if they are looping well,no drops or fallings, save like midifile and back to the keyboard.
If you want you can check my web site at www.topcities/music/vio for another way to make styles...Good luck
