Filter MIDI messages
You can lter 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 ltered out of any incoming MIDI data and are not sent
to the channel strip.
You can lter the following types of MIDI messages:
•
Pitch Bend
•
Sustain (control message 64)
•
Modulation (control message 1)
•
Expression (control message 11)
•
Aftertouch
Filter incoming MIDI messages
1 In the Channel Strip Inspector, click the MIDI Input tab.
2 In the Filter section of the MIDI Input tab, select the checkbox for the MIDI messages you want
to lter.
If you have created a controller transform, you can lter the input message type, and the
controller transform will still send its output message type. It is also possible to lter the output
message type, but in this case the output of the controller transform will be ltered.
Scale channel strip velocity
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 dierent parts of the key
range; for example, when a lter or attack parameter opens for higher note values to give a
brighter, sharper sound.
Open a velocity scaling graph
1 In the 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.
3 In the MIDI Input tab, do one of the following:
•
To open the velocity input graph: Select the Velocity Input button.
•
To open the note input graph: Select the Note Input button.
For information about editing the graph, see Work with graphs on page 62.
