🧠 Question Time: Do you know your envelope parameters?
When programming synths, tailoring sound design, or tweaking sampler envelopes, understanding ADSR is fundamental. Three of these controls dictate time, but one stands completely apart by controlling level.
Do you know which ADSR parameter actually controls volume level instead of time duration?

The Mechanics of the Envelope
It’s easy to group all four ADSR parameters together, but they operate on two completely different measurements.
Attack, Decay, and Release are all time-based controls measured in milliseconds or seconds. They dictate how fast a sound rises, drops, and fades out.
The single outlier in the group measures volume level, expressed in decibels. It determines the exact volume level your sound rests at after the initial attack and decay phases finish, holding that steady level for as long as the note is held down.
