Term
What does MIDI stand for?
Definition
Musical Instrument Digital Interface
Term
When was MIDI created?
Definition
1983
Term
What is a MIDI controller?
Definition
Any device that controls & sends information from MIDI device to computer
Term
3 universal components of MIDI
Definition
Keyboard, Pitch Bend Control and Modulation Control
Term
Four main functions of MIDI
Definition
Note on, Note off, Pitch, Velocity
Term
Aftertouch
Definition
A form of modulation once you touch the keys of a keyboard
Term
Multitimbral
Definition
Multiple patches that can play on one path
Term
MIDI Controller info is stored with a value of...
Definition
0-127, total value of 128
Term
What is a patch?
Definition
A preset of sound
Term
how many channels does MIDI have?
Definition
16 discrete
Term
Voices
Definition

How many notes you can play back at once

 

Term
MIDI modes
Definition
Omni On or Off, Polyphonic or Monophonic
Term
Most popular mode in MIDI
Definition
omni off/poly
Term
MIDI data flows parallel or serial?
Definition
serial
Term
Largest Value in any digital word is?
Definition
255
Term
MIDI words exist in what kind of bytes?
Definition
Status & Data
Term
How many bits per byte?
Definition
8
Term
Most Significant Bit is used to identify
Definition
Byte Type (status byte=1, data byte=0)
Term
Status Byte
Definition
what type of MIDI function is to be performed by a device or program (and also to encode channel data)
Term
Data Byte
Definition
used to associate a value to the event that's given by the accompanying status byte (aka value of how much the function is being changed)
Term
The last four numbers of a byte refer to
Definition
Which channel data is being sent to (i.e 10010000= Note on into channel zero) 
Term
Omni On/Poly 
Definition
Instrument will rspond to data from MIDI, redirect this data to the instrument's channel. The MIDI device will play back everything that is present at its input in a polyphonic fashion, regardless of incoming channel designation. This mode is rarely used. 
Term
Omni On/Mono
Definition
Instrument responds to all data received and redirects to device, device plays back all data regardless of channel and plays only one note at a time. This mode is the rarest OF ALL 
Term
Omni Off/Poly
Definition
Instrument only responds to data specific to the assigned base channel in a polyphonic fashion. Data assigned to other channels will be ignored. (i.e each of the 16 channels in a MIDI line could be used to independently play each part in a 16-voice, multitimbral synth). Most popular mode.
Term
Omni Off/Mono
Definition
An instrument will be able to respond to performance data that's transmitted over a single, dedicated channel; however each voice will only be able to generate one note at a time.
Term
SysEx
Definition
Saves specific data about parameters & program changes to be used with other (same) devices
Term
SysEx Dump
Definition
Dump presets from one devices to another. MUST be the same exact device
Term
Master/Slave relationship: When are masters used?
Definition
in situations where either sounds are not available on a Master Device or to create bigger sounds by combining multiple slaves into a chain. 
Term
What do you do when you want to send a voice from a MIDI controller through the OUT but don't want it to audibly play?
Definition
Turn Local Control Off (in order to turn a synth keyboard into a controller that only sends MIDI information and not actual music notes.)
Term
MIDI devices connect through a...
Definition
5 pin DIN (Deutches Institute for Normung)
Term
What part of the 5 pin DIN connector is not used
Definition
pin 1 & 3
Term
Maximum feet for MIDI cables?
Definition
50
Term
What 3 ports does MIDI send data through?
Definition
In, Out, Thru
Term
General MIDI
Definition
Set of patches laid in a fixed pattern, common to all devices (aka standardized patch set)
Term
MIDI Time Clock
Definition
Lock multiple devices to the same tempo, 96 pulses per measure)
Term
MIDI Interface is...
Definition
a way to convery MIDI performance information to the computer. The interface translates serial messages into a data structure that the computer can understand. USB or Firewire is most used nowadays, usually with 16 + I/Os.
