MST5K is a REAPER Script for the MIDI editor to aid in making and modifying note selections.
You can select by note range, velocity, length, and grid position, or any combination. There is a surprising amount of features packed into the interface with the info box at the bottom listing multiple functions available on each button through mouse modifiers.
While this tool does similar things to REAPER’s built-in MIDI Note filter, I’m finding for most tasks this is much easier to use.
