Use Note Repeat
It is possible to transform incoming MIDI notes into a repeated MIDI note of the same pitch, as long as the key is held down. You can define parameters such as repetition rate, velocity, and gate length, as well as assign MIDI controllers for controlling these parameters.
Transform incoming MIDI notes
Click the Note Repeat button in the toolbar (or use the corresponding key command).
In the initial Note Repeat dialog, you can do the following:
Choose a repetition rate from the Rate pop-up menu.
Define a velocity value in the Velocity field or leave it “As played” (which is the default).
Define a gate length value in the Gate field.
Click the disclosure triangle in the upper-left area of the dialog to reveal additional settings, then you can do the following:
Select the checkboxes to make the MIDI controller pop-up menus available, then choose a controller for rate, velocity, and gate time.
Define the maximum and minimum values for rate and gate time.
Define the maximum and minimum offset values for velocity.
Select the Key Remote checkbox in the lower-left area of the dialog to display the keyboard, then use the keys to define the rate and gate time settings.
The Note Repeat and Spot Erase keys have On/Off buttons, which offer the following functions:
When turned off (default), Note Repeat or Spot Erase is always active as long as the respective window is open.
When turned on, Note Repeat or Spot Erase is only active as long as the respective remote key is held down.
