Event Envelopes

Event envelopes give you the ability to control an audio event’s volume, fade-in, and fade-out.

NOTE If you've upgraded from Acid 1.0 or 2.0 software, you'll notice that event envelopes behave differently in version 2026. Use track envelopes for panning, effects levels, effect automation, and when you want to create multiple envelope points.
