APPENDIX A: GLOSSARY

MIDI: Musical Instrument Digital Interface. An

information protocol developed in the early 1980’s by

synthesizer and electronic instrument manufacturers to

allow devices to communicate musical performance data

to one another.

MTC: MIDI Time Code. A form of time code, digitized

within the MIDI format, that expresses time in hours,

minutes, seconds, and frames, just like SMPTE time code

(LTC and VITC).

Network: Two MIDI Time Pieces connected via their

NETWORK serial ports with a mini-DIN 8 cable.

Non-drop Frame: A SMPTE time code format that does

not drop any frames. Its counterpart, Drop Frame, skips

over the ﬁrst two frames of every minute (except every

10th minute). Non-drop is the least confusing format and

should be used unless Drop Frame is required. Drop-

frame is required only with color video programs in which

the SMPTE time code numbers must precisely match the

actual elapsed time.

NTSC: National Television Systems Committee Format. A

system of coding color information for broadcasting

television formulated by the NTSC. NTSC uses 30 frames

per second for black and white and 29.97 frames per

second for color.

Output cable: One of the eight (or sixteen) MIDI OUT

jacks in a MIDI Time Piece network.

PA L /S E CA M: Phase Alternate Line. A system of coding

color information that is similar to (but incompatible

with) NTSC format. PAL/SECAM uses 25 frames per

second.

Script: An itemized description of the commands that

make up a base setup or modiﬁer. The script is displayed in

the Setups & Modiﬁers window when the setup or

modiﬁer is selected.

Sequencer: A computer or software running on a

computer that is capable of recording and playing back

MIDI data.
