Shape the note
Bass · Lesson 2 of 4 · BS2
The 2nd step of the bass track in PatchPond's subtractive synthesis curriculum. Foundations; the filter is the star — and this lesson is where you meet amplitude adsr for the first time.
▸What you'll learn
A volume fader being moved by a robot every time you play a note — and you are programming the robot.
The amplitude envelope is the volume contour of a note from press to release. Four stages: Attack (how long to reach full volume after a key is pressed), Decay (how long to fall from peak to the sustained level), Sustain (the held volume while the key is still pressed), Release (how long the sound fades after the key is let go).
