To add a mod wheel controller event (#1) with a value that matches the note’s velocity
1 Choose the following settings in the Transform window:
• Mode menu: Copy selected events, then apply operations.
• Selection Conditions area: Set Status to Note.
• Operations area:
• Set Position to Add and enter a value of 1 in the field below it.
• Set Status to Fix and choose Control in the menu below it.
• Set Pitch to Fix and 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.
If you analyze these settings, you’ll see that all note events are selected for operation.
A copy of each is made, then moved 1 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.
2 Click Select and Operate.
This is automatically placed one tick after each note start and end, thus avoiding potential
conflicts with the note events themselves.
To create a transform set that fixes all note velocities to a defined amount
1 Select **Create Initialized User Set** from the Presets pop-up menu.
2 Set the Status menu in the Selection Conditions area to “=.”
3 Choose Note from the pop-up menu below.
4 Choose the Fix setting in the Velocity menu of the Operations area.
5 Change the amount to 127 in the value field below the Velocity menu.
