Protecting the Position of Events There are situations when you will want to protect certain events from being moved. For example, several note events may be used to trigger footstep samples that match an actor walking down a corridor, in a video soundtrack. You have already created the music for this scene, but have been asked to increase the tempo to match several cuts of different camera angles in the corridor. Obviously, a change in the project tempo will move the events, resulting in out-of-sync footsteps. Fortunately, Logic Express has a feature that preserves the absolute time position of events. To protect the position of one or more selected events µ Choose Functions > Lock SMPTE Position (or use the corresponding key command). This ensures that events that fall at a particular absolute time position-1 hour, 3 minutes, 15 seconds, 12 frames, for example-remain at this position when tempo changes are made. To unprotect the position of one or more events µ Choose Functions > Unlock SMPTE Position (or use the corresponding key command). Editing Events The list area features several columns: Position, Status, Ch(annel), Num(ber), Val(ue), and Length/Info. These columns display all details of all event types. In most cases, you can directly edit the data displayed (with the exception of the Status column, which merely indicates the event type). Not all columns are used for every type of event. For example, system exclusive messages are not MIDI-channel specific, so the Ch(annel) column is unused. Channel and polyphonic pressure messages have no length, so the Length/Info column is left blank. 708 Chapter 25 Editing MIDI Events in the Event List

Protecting the Position of Events

There are situations when you will want to protect certain events from being moved. For

example, several note events may be used to trigger footstep samples that match an

actor walking down a corridor, in a video soundtrack.

You have already created the music for this scene, but have been asked to increase the

tempo to match several cuts of different camera angles in the corridor. Obviously, a

change in the project tempo will move the events, resulting in out-of-sync footsteps.

Fortunately, Logic Express has a feature that preserves the absolute time position of

events.

To protect the position of one or more selected events

Choose Functions > Lock SMPTE Position (or use the corresponding key command).

This ensures that events that fall at a particular absolute time position—1 hour, 3 minutes,

15 seconds, 12 frames, for example—remain at this position when tempo changes are

made.

To unprotect the position of one or more events

Choose Functions > Unlock SMPTE Position (or use the corresponding key command).

Editing Events

The list area features several columns:

Position, Status, Ch(annel), Num(ber), Val(ue), and

Length/Info. These columns display all details of all event types. In most cases, you can

directly edit the data displayed (with the exception of the Status column, which merely

indicates the event type).

Not all columns are used for every type of event. For example, system exclusive messages

are not MIDI-channel specific, so the Ch(annel) column is unused. Channel and polyphonic

pressure messages have no length, so the Length/Info column is left blank.
