Chapter 5 Capturing and Editing Digital Audio Part 3 Music Creation
In this lecture, you will learn: the basics of creating music using MIDI the basics of creating music by composing loop music
Types of Music Creation MIDI: create original music scores require musical composition skills Loop music composition compose a long musical audio through repetitions of short musical clips common in projects that do not require a long musical score, for example: game development, product advertisements, digital art projects allow non-music composers to create musical audio
MIDI Not sampled audio Like sheet music Constains instructions for recreating the music Created by editing music notations and instrument assignments Can also be created by recording your performance on a MIDI keyboard connected to a computer Playback of a MIDI file requires a sound card that uses the synthesizer to recreate the sound of notes
MIDI Programs Cakewalk SONAR Steinberg Cubase MakeMusic! Finale
Views in Cakewalk SONAR Staff view: to work with notation and staff Piano Roll view: to visualize notes as they would appear on a player-piano roll Event List view: to work with a sequence of MIDI information
Cakewalk SONAR Staff View to work with notation and staff
Cakewalk SONAR Piano Roll View to visualize notes as they would appear on a player-piano roll
Cakewalk SONAR Event List View to work with a sequence of MIDI information
Cakewalk SONAR Assigning an Instrument to a MIDI Track
MIDI Playback Requires a sound card that uses the synthesizer to recreate the sound of notes Not all synthesizers produce the same sound Disadvantage: How the music actually sounds during playback depends on the sound card
Loop Music
Loop Music Music that is created from short music clips that are repeated Usually designed to loop seamlessly Libraries of clips for loop music are commercially available
Loop Music Example Programs Sony ACID Pro (Windows) Apple GarageBand (Mac OS) General digital audio editing programs: Adobe Audition Audacity
Composing Music Using Loop Music Programs support multi-track Import an audio clip to place on a track Create repetitions of a clip placed on a track simply by dragging its right edge to extend it You can adjust the volume of each track to fade in or out the clips
Sony ACID Pro 3 repetitions 2 repetitions
Apple GarageBand 2 repetitions 1.5 repetitions 2.5 repetitions
Adobe Audition 3 repetitions In mulltitrack view, set the loop option for a clip. Extend its duration to create repetitions.
Audacity Use the effect called Repeat Repeat a selection of the audio for a specified number of times
Review Questions Note to instructor: Depending on your preference, you may want to go over the review questions at the end of this lecture as an instant review or at the beginning of next lecture to refresh students' memory of this lecture.
Review Question ___ deals with notations, staff, and musical instrument assignments. MIDI loop music A
Review Question What is the disadvantage of MIDI compared to composing music with loop music? How exactly the playback of the MIDI music sounds depends on the sound card that plays it. Thus, you do not have control over how exactly it sounds when other people play your MIDI file.
