Controller Information

Top  Previous  Next

You can edit MIDI controller data on the bottom portion of the Piano Roll Editor on the Sound tab.




hmtoggle_arrow1 Choose The Controller Type


Click the drop down on the left hand side to pick a specific controller.

You can choose from the following controller types:


Note On Velocity

Note Off Velocity

Program Change

Channel Pressure

Pitch Wheel



Alternatively, you can type in a controller number from 0 to 127.


If the clip has controller information for a specific controller, the controller will appear in bold in the drop down list.


hmtoggle_arrow1 Editing Controller Data


There are two modes in the controller window:





Select the eraser button to erase controller data and select either the arrow or pencil tool to draw controller data.


In this example, we are going to modify the velocity of the notes so that it ramps up.  Here is the way it looks initially.  Each line represents the velocity of the note in the piano roll above.




Now we click down and drag the mouse to draw the following shape.  The dark blue represents the area we have drawn.




If you need more room or pixels to edit the controller data, simply click on the bar at the top of the controller area and drag it up or down to re-size the controller area.



The selected note's corresponding velocity line appears in red.


hmtoggle_arrow1 Editing Velocities Of Selected Notes


You can edit the selected note's velocities by holding down the SHIFT key and drawing over the velocities.  This can be extremely useful because if you have notes that start at the same time, it is sometimes very difficult to adjust the velocities of one note and not of the other.


The selected note's velocities show up as red bars.  Hold down the SHIFT key and drag over the velocities to draw/edit the selected notes only.


Shift click drag to alter selected note velocities only


Note that only the velocities of the selected Ab notes are being edited.


hmtoggle_arrow1 Precise Editing Of Controller Information


Sometimes you may want to edit a controller to a specific value, but it is too difficult to move your mouse to the exact pixel on the screen.


For all controllers, besides Velocity, you can right click to add, edit or delete controller information.


The options that will appear on the right click menu are:


Add Controller

Edit Controller

Delete Controller

Delete All Controllers


For example, if you want an external synthesizer to switch to patch 67, choose the "Program Change" controller, move to the start of the track, right click and select "Add Controller" from the menu.  A dialog box will pop up and allow you to type in 67. Click OK and you will now have a program change #67.
