MIDI Transform window examples
This section provides several usage examples for the MIDI Transform window.
Add a mod wheel controller event (#1) with a value that matches the note’s velocity
1 Choose the following settings in the MIDI Transform window:
•
Mode pop-up menu: Copy selected events, then apply operations.
•
Selection Conditions area: Set Status to Note.
•
Operations area:
•
Set Position to Add, then enter a value of 1 in the field below it.
•
Set Status to Fix, then choose Control in the pop-up menu below it.
•
Set Pitch to Fix, then enter a value of 1 in the field below it. This means “the first data byte
receives the value of 1” (the first data byte defines the controller number for controller
events, and mod wheel events happen to be #1).
Note: When you convert MIDI note events to controller events, two controller events are
created: one for the note on event, and one for the note off event.
2 Click Select and Operate.
If you analyze these settings, you’ll see that all note events are selected for operation. A copy of
each is made, then moved one tick later than the original, and converted to CC#1 (mod wheel),
with a value that corresponds to the velocity of the original note. This is because the second data
byte (Vel) is left unaltered.
The automatic offset by one tick after each note start point and end point avoids potential
conflicts with the source note events.
Create a transform set that fixes all note velocities to a defined amount
1 Choose Create Initialized User Set from the Presets pop-up menu.
2 Set the Status pop-up menu in the Selection Conditions area to “=.”
3 Choose Note from the pop-up menu below.
4 Choose the Fix setting in the Velocity pop-up menu of the Operations area.
5 Change the amount to 127 in the field below the Velocity pop-up menu.
