182 Chapter 8 Basic Operations
Selecting Events With the Same MIDI Channel
Following selection of an event, you may select all other events that share the same
MIDI channel by using the Edit > Select Equal Channels command (default key
command: Shift-K).
As an example: Imagine you’re editing a MIDI region that contains volume and pan
controller information for 16 MIDI channels.
To select all events on channels 1 and 3:
1 Shift-select one event on channel 1 and another event on channel 3.
2 Choose Edit > Select Equal Channels (or use the corresponding key command,
default: Shift-K).
All other events on these two channels will be selected.
Selecting Regions or Events With an Equal Subposition
You can select all regions and events with a certain relative position, such as all snare
drums on the off-beat. Select a region or event at the desired relative position, and
choose Edit > Select Equal Subpositions (default key command: Shift-P). All regions or
events with the same relative position will be selected.
Accelerating Edit Operations With Selection Commands
As you can see, there are many different ways to make selections, based on different
criteria. These can be used to speed up many editing operations, in conjunction with
key commands. Here are a few examples:
If you want to delete all similar regions, events, or objects, make your selection and use
the Delete Similar Object key command.
Conversely, if you want to keep all similar regions, events, or objects, and delete all
others, use the Delete but Keep Similar Objects key command.
You can use the Event Channel +1 key command or the Event Channel –1 key
commands to alter the channel number of the selected event (or events) by one,
making it easy to reassign it/them to another MIDI channel.
