I am needing a web app that will parse a MIDI file, and display the contents using png images that represent the notes, and another set of png images to represent the durations. Please have familiarity with MIDI and music. If you know the definitions of the following words, please apply: Octave, Key, BPM, Quarter Note, Rest, Note On, Velocity I will give more detailed specifications once I am confident you have a basic knowledge of music and MIDI, and the programming skills. Please describe the work you have done with music in your application.
