Latest revision as of 06:37, 30 January 2020

First, review the lecture slides. 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).
