1. Circle 3 answers that are accurate statements about MIDI interfaces:

a - they typically connect to a computer using MIDI connectors

b - they typically connect to a computer using USB connectors

c - they pass synthesizer audio data back and forth between controllers, computers, and synthesizers

d - they pass MIDI performance data back and forth between controllers, computers, and synthesizers

e - they are sometimes built in to keyboard controllers and audio interfaces

f - they should not be used with more than 16 MIDI channels at once

 

 

 

2. The one type of MIDI interface not recommended for professional use is:

a - single port interfaces

b - interfaces built into keyboard controllers

c - MIDI interfaces built into audio interfaces

d - MIDI interfaces built into standard PC sound cards

 

 

 

3. A MIDI “in” connector would usually be used for:

a - sending MIDI data into a synthesizer or MIDI interface

b - sending MIDI data into a keyboard controller

c - sending MIDI data into a synthesizer, but never into a MIDI interface

d - sending MIDI data into a MIDI interface, but never into a synthesizer

 

 

 

4. A MIDI “out” connector would usually be used for:

a - sending MIDI data out of a synthesizer and into a keyboard controller

b - sending MIDI data out of a MIDI interface and into a keyboard controller

c - sending MIDI data out of a keyboard controller and into a MIDI interface

d - sending MIDI data out of a keyboard synthesizer and back into its own MIDI input, for the popular MIDI feedback effect

 

 

 

5. A MIDI “thru” connector would usually be used for:

a - adding ports to a MIDI interface

b - sending MIDI data generated by one synthesizer into another synthesizer

c - “daisy - chaining” MIDI interfaces

d - “daisy - chaining” synthesizers

 

 

 

6. A single MIDI “port” can:

a - carry up to 16 voices of MIDI data

b - carry up to 16 channels of MIDI data

c - carry only one channel of MIDI data

d - carry up to 128 channels of MIDI data

 

 

 

7. Circle 3 answers that could correctly complete this statement - “MIDI data:

a - uses a serial interface

b - uses a parallel interface

c - uses a bilateral interface

d - is uni-directional (only flows in one direction through a given MIDI cable)

e - is bi-directional (flows in both directions through a given MIDI cable)

f - travels at a rate of 31.25 kbaud (bits per second)

g - travels at a rate of 31.25 kbaud (bytes per second)

h - travels at a rate of 31.25 ghz

 

 

 

8. Most MIDI messages:

a - contain data about synthesizers parameters

b - contain data values with a range of 0-127 (except pitch bend->human ear is very sensitive to pitch change)

c - do not use binary codes

d - contain data values which read the same forwards and backwards

 

 

 

9. Circle 3 answers that could correctly complete this statement - “A MIDI note-on message contains:

a - data about the velocity of a note

b - data about the duration of a note

c - four bytes of data

d - data about the pitch (note number) of a note

e - data about the polyphony of a note

f - data about the MIDI channel of a note

g - data about the MIDI port of a note

 

 

 

10. Circle 2 answers that could correctly complete this statement - “MIDI note velocity:

a - has a variable effect, depending on the synth program

b - always effects loudness

c - measures the speed of key depression

d - measures the duration of a held key

e - has a range of values from -8,192 to 8191

 

 

 

11. Circle 3 answers that could correctly complete this statement - “A MIDI pitch bend message:

a - has a range of values from 0 to 127

b - has a range of values from 0 to 8,191

c - has a range of values from -8,192 to 8,191

d - always has a range of plus and minus 2 semi-tones (half-steps)

e - has a variable range, depending on the synth program

f - is made up of 1 status byte and 2 data bytes (1 byte for note #, 1 byte for velocity)

g - is made up of 2 status bytes and 2 data bytes

h - is made up of 1 status byte and 1 data byte
