I see where you are coming from, however the only time I use Midi files, is if I need the score, which can be produced from most Midi Sequencers. (NOTE: If your keyboard does Midi markers then you can use it as a Midi style, or indeed convert it into a style)

The arrangement sounds okay to me, however music is such a personal thing, only you can decide if it suits.

As it’s a free download, why not just download it and see if it suits your need.

Hope this helps
