MIDI is data, not audio. It sends messages like 'note C4 velocity 100'. The synthesizer or sample library generates the actual sound from that instruction.
Question 2 True / False
True or false: MIDI data can only be sent between one pair of devices.
TTrue
FFalse
Answer: False
MIDI supports 16 channels per cable, and multiple devices can communicate via MIDI hubs, allowing complex instrument chains and multi-channel productions.
Question 3 Short Answer
What is a program change in MIDI?
Think about your answer, then reveal below.
Model answer: A MIDI message that switches between preset sounds on a synthesizer or instrument without interrupting the performance.
Program changes let you switch synth sounds mid-sequence without manually adjusting parameters. Combined with bank select (CC0/CC32), they access large libraries of presets.
Question 4 Multiple Choice
What are control change (CC) messages in MIDI?
AMessages that switch sounds
BMessages that modulate continuous parameters like volume, filter cutoff, or modulation wheel
CMessages that control recording
DOld MIDI messages no longer used
CC messages let you automate continuous parameters. CC7 = volume, CC1 = modulation wheel, CC74 = filter cutoff. They are essential for expressive, dynamic MIDI performances and automation.
