Filtering MIDI Messages
You can filter some MIDI messages for a channel strip in the Channel Strip Inspector.
When you select one or more MIDI message types in the Filter section of the Channel
Strip Inspector, the corresponding MIDI message types are filtered out of any incoming
MIDI data and are not sent to the channel strip.
You can filter the following types of MIDI messages:
 Pitch Bend
 Modulation (control message 1)
 Aftertouch
 Sustain (control message 64)
 Expression (control message 11)
To filter incoming MIDI messages:
m
In the Filter section, select the checkbox for the type of MIDI messages you want to
filter.
If you have created a controller transform, you can filter the input message type, and
the controller transform will still send its output message type. It is also possible to
filter the output message type, but in this case the output of the controller transform
will be filtered.
Deleting Channel Strips
You can delete a channel strip if you decide you no longer want it in a patch.
To delete a channel strip:
1
Select the channel strip in the Channel Strips area.
2
Choose Edit > Delete (or press the Delete key).
Mapping Screen Controls
After you have chosen the channel strip settings you want to play, you can map
MainStage screen controls to channel strip parameters or map them to MainStage-
specific actions or to AppleScript scripts. For information about assigning physical
controls to screen controls in the workspace, see “
