Question 1

What are System Exclusive (sysex) messages used for in the MIDI protocol?

Answer 1

Systems Exclusive

A type of MIDI system message compatible with one specific piece of gear. System Exclusive messages are used to carry proprietary control information, to control parameters that can’t be accessed with continuous controller messages, and to transfer RAM program data between synthesizers and other MIDI-compatible gear.

Question 2

What is the style of synthesis where the modulator modulates the frequency of the carrier?

Answer 2

Frequency modulation (FM)

Question 3

What is the style of synthesis where the modulator modulates the phase of the carrier?

Answer 3

Phase Modulation (PM)

Question 4

What are the styles of synthesis where the modulator modulates the amplitude of the carrier?

Answer 4

Amplitude modulation (AM)

Question 5

What is a tempo map?

Question 6

What is MIDI beat clock?
What is automation and why is it useful for an audio engineer?

Answer 6

A list of tempo changes that occur during a piece of music held as a list in a tempo track of a DAW

Question 7

What is MIDI beat clock? aka MIDI timing clock

Answer 7

a signal that is broadcast via MIDI to MULTIPLE devices to ensure that these MIDI-enabled DEVICES stay in SYNCRONIZATION

Question 8

What is automation and why is it useful for an audio engineer?

Answer 8

Automation is the control of the computer to record changes to switch positions, faders moves, and other statuses and have them play back with the audio recording.

It is useful to an audio engineer so they can recall accurate, repeatable, and recallable control of previous MIDI performances over a mixer or performance.

Question 9

Briefly describe how touch mode automation works.
.

Answer 9

Touch mode returns back to the original fader position when the automation parameter is released.

Question 10

Briefly describe how latch mode automation works

Answer 10

Latch mode remains at the SAME location when the automation parameter is released.

Question 11

Briefly describe how write mode automation works.

Answer 11

Write mode will overwrite any previous automation when the automation parameter writes new parts over.

Question 11

In touch/Latch, the panning and plug in automation operate in touch mode while volume faders operate in latch?

Question 12

The intraframe video format is considered an editing format?

Answer 12

Yes ,
intraframe codecs are often used in editing and are considered an editing format.

Question 13

In Fm synthesis, the oscillators are called?
Additional frequencies created by FM synthesis are called?

Answer 13

a. modulators
b. sidebands: are harmonically related to the carrier and modulator, and appear symmetrically around the carrier frequency.

Question 14

Compare the control surface protocols HUI and Leucon, what are the main differences between them?

Answer 14

HUI stands for human user interface which connects the DAW specifically Pro Tools to the control surface. EUCON also is a more advanced protocol including HUI which can operate across multiple DAWs.

Question 15

How is pitch bend protocol used in HUIU surfaces? Why?

Question 16

List at least 3 things you can do to help your DAWS video engine operate smoothly.

Question 17

What are ticks regarding MIDI? What is the default name of ticks given in Pro Tools?
What is the general reason to use CC#11 (expression) rather than MIDI CC#7 (volume) in MIDI performances?
What is swing? What do the swing note value and swing percentage settings dictate?
How would you personally utilize a control surface in your own personal workflow? Be specific in detailing how your workflow would benefit or change from utilizing a motorized control surface.

Question 18

What is the general reason to use CC#11 (expression) rather than MIDI CC#7 (volume) in MIDI performances?

Question 19

What is swing? What do the swing note value and swing percentage settings dictate?

Question 20

How would you personally utilize a control surface in your own personal workflow? Be specific in detailing how your workflow would benefit or change from utilizing a motorized control surface.

Question 21

n regard to FM or PM synthesis, If the modulator ratio is 4:1 an the MIDI Keyboard is telling the operators to play 1000hz, what frequency is the modulator generating, and what frequency is the carrier generating? What kind of tone is FM and OM synthesis most known for?
