Adjusting MIDI controller automation settings

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.

For more information, see Setting up MIDI message input filters on page 205.

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.

For more information, see Using MIDI merge recording on page 192.

MIDI program change automation

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

For more information, see Adding a program change keyframe on page 210.

Adjusting envelopes

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.

Tip: If you have multiple envelopes on a track, hover over an envelope to display a tooltip indicating the name of the envelope.

Adding envelope points

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.

1.Place the mouse pointer on the envelope line. The envelope cursor () appears.

2.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.

Tip: 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.
