Blackberry Bold Midi

I'd like a midi application written in Java for my Blackberry Bold. I'd like to be able to select from 2 instruments and input a line of text for each which will then convert to a midi sequence that can be played. When the ‘P’ button is pressed the sequence will play and when the ‘S’ button is pressed it will stop. Each number represents the midi note itself and a comma represents a pause. See attached for a screen shot demo.
