I tried playing an easy piano accompaniment for a verse on the midi in the song that I am currently working on.
I recorded it in EZK and then exported to a midi file.
I then brought that midi file back into EZK and tried applying EZK styles and variations to the midi.

(Saw all this in a video)

My result was terrible. Just sounded like a mess with no connection to the original song.

If you give something like that a shot and get a good result...please let me hear it and share how you did it.
