MIDI Playback Four Principal Systems: 1.Hardware Based Wave Tables
This is what you find in the $100-$400 keyboards.
2. Software Based WaveTablesThis is what you find in many computer sound cards.
3. Frequency Modulated Synthesis
This is the technology pioneered by Yamaha and still used in their moderately priced hardware.
3. Sampled Sound Wave Tables These use samples of real sounds for very realistic playback. Can
be hardware or software based. Some computer sound cards use hardware based sampled sounds.

Available from Amazon.com for $200/each

Using MIDI Data
Midi files can be:
Converted to musical scores using programs such as Scorewriter
Modified using programs such as Cakewalk’s Home Studio or Music Creator
Converted to an MP3 file
Converted to a .WAV file and burned into a CD to be played on standard audio equipment
•e-mailed to a friend
Used for “live” performance through a “Tone Generator” or synthesizer

Manipulating MIDI data in Score Writer
•Edit/Midi Data
Velocity (=loudness)
Wheel (pitch change within a note)
Control – Pan (stereo – left to right)
Control – Expression (loudness change within a note)
Tempo
Cakewalk’s “Music Creator” contains greater capabilities for editing MIDI data and is a nice companion program to Score Writer.

Getting Sound Out
• MIDI doesn’t make sound
• MIDI tells a device when to make a sound andwhat sound to make
• There are many devices which make sound inresponse to MIDI instructions
