Track-level MIDI input filters—available on the Input Filters tab in the Track Properties window—allow you to control exactly which
MIDI messages you want to record or exclude.

You can also use an external MIDI controller (or the keyboard/drum list between the track header and timeline) to record MIDI into your
ACID project.

You can use keyframes to change the track voice throughout your project. 

Envelopes represent volume, audio panning, bus send levels, effect send levels, MIDI controllers, and effect parameter automation 
settings in the timeline.

To adjust the overall level of an envelope, simply drag the envelope line up or down. A tooltip displays the amount of the adjustment as 
you drag. You can adjust envelopes in real time. 

You can also change the level of an envelope over time by adjusting individual envelope points that you place along the envelope line. 

After you have inserted an envelope, you can add envelope points to control the level of signal or amount of panning at specific points 
in time. 

Place the mouse pointer on the envelope line. The envelope cursor ( 

) appears. 

Add an envelope point in one of the following ways: 

• 

Double-click the envelope. 

• 

Right-click the envelope and choose Add Point from the shortcut menu. 

 If you add too many points, you may delete a point by right-clicking it and choosing Delete from the shortcut menu. You may also 

clear all envelope points by selecting Reset All from the shortcut menu.
