Let's just discuss this here or via email... either is fine with me.
If you think you have a feel for how the steel drums may go, you probably want to send me the midi file sooner than later... because what you send may not translate at all like you think it will.
I have never tried steel drums nor do I have any midi rhythms and of all things I can imagine this being a bit of a process to get it sounding authentic.
In fact if you even have chord changes over X number of bars, it might help to have a chart.
