SYNCHRONIZATION

1. SYNCHRONIZATION BASICS
2. MIDI
3. OPEN DISCUSSION

A. BASIC SYNCHRONIZATION TECHNIQUES

1. synchronization
a. basics

– read sync paragraph (p. 371)
– multiple-machine operation

b. time code
– SMPTE/EBU time code basics
– what is a TC “address” (p. 372)
o encoded onto magnetic tape (bi-phase)
o 00:00:00:00 (MIDNIGHT!!!)
– Frame Standards (p. 374)
o 30 fr/s b&w (non-drop frame)
o 25 fr/s EBU (Europe)
o 29.97 fr/s color (drop frame)
o 24 fr/sec film
– LTC
o can be read at fast, play and slow speeds
o video (window dub)
– VITC
– can be read at extremely slow and stop-frame speeds, due to rotary head video design

c. the time code synchronizer
– MASTER/SLAVE architecture
o Who’s the master? (page 386)
o audio/audio & audio/video synchronization

d. digital video’s need for precise timing
– House sync (black burst)

e. MTC (MIDI time code)
– synchronous MIDI/SMPTE operation
– enables time code to be distributed thoughout the MIDI chain
– 1/4 frame & other messages

f. Broadcast Wave (imbeds timecode within the soundfile stream)

g. MIDI timing clock
– very important to electronic musicians
– internal/external clock

h. Digital Audio Sync
– Not a time code structure at all … (digital’s need for exact relative timing)
– Digital word sync (non-TC sync) is often imbeded within word
– embedded structure allows simple timing sync between digital devices when copying

i. Word Clock (a different animal)
o Need for a precise clock lock
o clicks and pops

MIDI

1. What is MIDI?
2. what MIDI isn’t
3. why is MIDI

MIDI Channels

4. The MIDI Message
– exploring the spec
– byte structure (note on example)

– the digital word

6. Intruments
– Keyboards
– Synth
– analog
– digital
