This envelope shaping is crucial in synthesizers and virtual instruments, as it allows for dynamic control over the amplitude and timbre of a sound, making it more expressive and musical.
Control change: Control change refers to the process of sending specific messages within the MIDI (Musical Instrument Digital Interface) protocol to modify parameters of musical performance, such as volume, pan, effects, or other instrument settings. These messages allow for real-time adjustments and dynamic expression in music production, enabling performers to manipulate various aspects of their sound during playback or live performance.
Envelopes: Envelopes refer to the dynamic changes in sound parameters over time, particularly in the context of amplitude and timbre. They are crucial for shaping how a sound evolves from the moment it is triggered until it stops, influencing aspects like attack, decay, sustain, and release (ADSR). Understanding envelopes allows musicians and producers to create more expressive sounds by controlling these elements within MIDI controllers and virtual instruments.
