MIDI file creation

Create a MIDI file with at least 25 MIDI messages.

Incorporate at least 4 of the following features into the MIDI file:

• Type-1 MIDI file (multi-track)
• Patch change (timbre/instrument change)
• Pitch bend (glissandos, temperament)
• Articulations (accents, staccato/legato)
• Continuous controller (master volume, pan)
• Meta message (tempo, key signature, time signature, track name)
• Percussion sounds
• Chords

Send me a copy of the MIDI file (and the text representation) by next Thursday's class so we can play them.

Examples

Here are examples from class that can be used as a reference.

Idea: Try creating a type-1 MIDI file, and add a bass line to the melody using this score: http://imslp.org/wiki/12_Variations_on_%22Ah,_vous_dirai-je_maman%22,_K.265/300e_(Mozart,_Wolfgang_Amadeus)

Adding a patch change

Here is a list of General MIDI instruments: http://www.ccarh.org/courses/253/handout/gminstruments

Note that you need to subtract 1 from the instruments in that list for the patch change. Remember that the page change is the hex byte C0 (for changing the instrument on channel 1).
