Set a software instrument as unpitched
1. Select the channel strip in the MainStage Channel Strips area.
2. In the MIDI Input tab of the Channel Strip Inspector, select the Unpitched checkbox.
The software instrument’s output remains unpitched even if the rest of the patch
receives transposed MIDI notes.
Filter MIDI messages in MainStage
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
• Channel Aftertouch
• SysEx
• Continuous Controller (CC) messages 0-127
Filter incoming MIDI messages
1. In the MainStage Channel Strip Inspector, click the MIDI Input tab.
2. In the Input Controller section of the MIDI Input tab, select the checkbox for the MIDI
messages you want to filter.
If you have created a controller transform, you can filter the input message type, and
the controller transform still sends its output message type. It is also possible to filter
the output message type, but in this case the output of the controller transform is
filtered. See Create controller transforms in MainStage for more information.
Scale channel strip velocity in MainStage
You can scale the output velocity of a channel strip using the Velocity Scaling graphs. You
can scale output velocity based on note input or input velocity.
When you perform velocity scaling, each input velocity (regardless of the note being
played) is scaled to the output velocity.
When you perform note scaling, output velocity is scaled depending on the note in the key
range. This is useful when you want to have a parameter change in different parts of the
key range; for example, when a filter or attack parameter opens for higher note values to
give a brighter, sharper sound.
Open a velocity scaling graph
1. In the MainStage Channel Strips area, select the channel strip on which you want to
perform velocity scaling.
2. In the Channel Strip Inspector, click the MIDI Input tab.
