I have Reaper 4.261 and am trying to view the controller data (specifically for the sustain pedal). I've tried reading the manual, but it didn't help much.

How do I view the controller data in Reaper?

In Reaper, you can view controller data in the MIDI editor.

To open the editor, right click on the MIDI track you wish to view and select Built-in MIDI editor->Open in editor.

enter image description here

In the MIDI editor there is a drop down list in the lower left corner. Select 64 Hold Pedal (on/off). You should see the sustain pedal controller data in the bottom portion of the window.
