Q

Is MIDI Machine Control (MMC) a synchronisation protocol?

A

No; it’s not a protocol - it goes hand in hand, but it enables transmission of one device’s transport controls over a MIDI cable (controller)

Q

Fundamental difference between LTC and MTC

MTC - MIDI signal

21
Q

Resolution of MIDI (Beat) Clock

22
Q

SMPTE framerate used for color video production in the US

23
Q

Sync signal used to synchronise two or more MIDI sequencers together

A

MIDI clock

24
Q

2 types of sync signals that can be recorded on an analog MTR

A

LTC and FSK

25
Synchronisation
Multiple devices working together over time
26
MMC
MIDI Machine Control - Transports commands, MIDI messaging from one device to another over a MIDI cable. Comparable to the remote of the MTR-90, ergo 'control - controller'
27
SMPTE pulse, or subdivision of one second in timecode
Frames
28
3 primary sound elements in film and television production
Dialogue, music, and sound effects
29
PPQ
Pulses Per Quarter Note - the number of messages sent from the master to the slave every quarter note giving information.
30
Pace
How fast/slow we are going: time, tempo, pulses, etc
31
Place
Where we are starting from: measures, location, timestamp, etc
32
How is device synchronisation similar to an ensemble?
Everyone needs to know where to start, when to start, and at what speed in order to play altogether; and this is all achieved by many individuals (slave devices) following cues from the conductor (1 master device)
33
Simultaneous vs Synchronisation
Just because two things happen at the same time (simultaneous), doesn't mean they are synchronised. Synchronisation requires working together COMMUNICATION of two things: pace and place
34
Is a MIDI controller telling another device what to do synchronisation?
No - there is no communication of maintaining time, tempo, etc (pace)
35
Real time protocols
Goes by hours, minutes, seconds | SMPTE
36
3 types of SMPTE protocols
LTC - audible version MTC - MIDI version VITC - video version
37
Musical time protocols
Goes by bars, beats MIDI Beat Clock FSK
38
MIDI Beat Clock vs MTC
MIDI Beat Clock uses PPQ beats for pace and place | MTC uses hours:minutes:seconds:frames for pace and place
39
"Name" of the EU video standard
PAL
40
Sync mode setting of the Master
Internal
41
Sync mode setting of Slave
External
42
Protocol used between analog devices
LTC
43
Protocol used between analog and digital
MTC
44
Protocol used between MIDI sequencer and analog/digital
MIDI Beat Clock
45
