 1. MIDI (Musical Instrument Digital Interface) - used to record synthesised music on your computer system 
Note: Have a read of the wikipedia entry on MIDI before attempting this quiz.

  FALSE

  TRUE

 2. A keyboard is usually used with each note in a tune having a set of attributes which the user can then ____________________

  delete

   edit, save and play back.

  convert to PNG format

  save as an analogue file

 3. Common attributes of notes stored as MIDI data include:

  Pitch (Frequency of the note, height or depth of note)

  All of the above are valid

  Volume (how soft or loud the note is played)

  Instrument (which instrument is being played)

 4. MIDI is an agreed ________ from the early 80s that allows computers, digital musical instruments and other hardware to communicate musical instructions, regardless of manufacturer.

  protocol

  instrument

  formatting type

  musical note

 5. MIDI is different in that it only stores or transmits commands about the music (the notes etc), and not ___________________

  None of the above

  individual notes

  audio signals.

  analogue waves

 6. Notes (events) are instructions and include:

  Modulations

  Pitches or notes played

  All of the above are valid

  Tempo

 7. A MIDI controller is a piece of hardware or software that creates and transmits MIDI data to other MIDI devices.

  FALSE

  TRUE

 8. To record or edit a MIDI project, a ___________ is also needed. A _________ will send playback instructions (data) to any connected and compatible output components

  sequencer

  audio converter

  None of the above

  analogue modem

 9. MIDI is a recording of actual audio and not a recording of data events.

  TRUE

  FALSE

 10. Why is it possible to edit MIDI easily and play it back to sound like any instrument?

  It isn't

  None of the above

  Because MIDI is a recording of data events not actual audio

  Because MIDI uses actual instruments and real strings in its audio transfer

 11. MIDI - when stored - has a very large file size

  TRUE

  FALSE

 12. MIDI represents only the playback information and not the audio itself. (this helps with file sizes)

  TRUE

  FALSE

 13. Advantages of MIDI include:

  wide choice of electrical instruments and digitally sampled sounds

  small file size

  ease of modification and manipulation

  All of the above are valid

 14. MIDI was invented so that electronic or digital musical instruments could communicate with each other and so that one instrument can ________________

  None of the above

  delete all wave sounds

  control another

  easily be converted into images

 15. Because MIDI is a set of commands that create sound, MIDI sequences can be manipulated in ways that prerecorded audio cannot

  TRUE

  FALSE

 16. The ___________________ is a file format that provides a standardized way for music sequences to be saved, transported, and opened in other systems.

  Standard MIDI File (SMF)

  SM3 (Standard Midi 3)

  Creative Old Midi (COM)

  MIDI player 3 (MP3)

 17. A MIDI file is not an audio recording. Rather, it is a set of instructions – for example, for pitch or tempo.

  FALSE

  TRUE

 18. MIDI can use a thousand times less disk space than the equivalent recorded audio

  FALSE

  TRUE

 19. Computers can use software to generate sounds, which are then passed through a digital-to-analog converter (DAC) to a power amplifier and loudspeaker system

  TRUE

  FALSE

 20. Early PC games were distributed on floppy disks, and the small size of MIDI files made them a viable means of providing soundtracks

  FALSE

  TRUE
