By using the NumPad keys to move the position of the highlight bar and Edit Cursor, and the Function keys to enter notes, complete arrangements can be quickly created using the Keyboard alone. F5 has been pressed in sequence, creating an E note.

In the example above, the starting pitch for F1 is C5. The starting pitch for F1 is determined by the location of the highlight bar. The function keys are mapped to the 12 Semitones of an Octave, with F1 having the lowest pitch and F12 having the highest pitch. When enabled, the function keys (F1 - F12) can be used to enter notes. Note: Only works when using a vsti that reports note names, such as in this example, Fxpansion's BFD. Replaces the Piano Roll view with note names. In the picture below, you'll see the Timeline cursor at 4:00 while the MIDI Editor cursor is at 1.Дisplays a standard, white/black piano key view. When disabled, each ruler can display different parts of the song. Very helpful in synchronizing MIDI tracks to audio tracks in the project. When enabled, the MIDI Editor Ruler displays the same information as REAPER's main Timeline Ruler. This option tells REAPER to display the note name on each MIDI event. Useful for quickly comparing and adjusting event velocities. This option tells REAPER to display a velocity control on each MIDI event. With this option enabled, REAPER plays whatever VSTi or MIDI instrument is assigned to that track through the FX box or hardware routing (providing monitoring is on). This option is great for previewing single notes as you enter them. If you want to preview a single pattern, uncheck this option. Synchronizes the transport of the MIDI Editor to REAPER's main Timeline. Sync Editor Transport to Project Transport Positions the midi editor inside the Docker. Repositions selected MIDI events so they're reversed in relation to each other from their original positions. See this page for more detailed info on the Quantize feature: Quantize Menu

Disabling Snap allows you to make very accurate splits: Splits any note currently located under the mouse cursor (based on snap settings). If no notes are currently selected, all notes currently under the Edit Cursor are split.Д¬ursor over midi notes, none selected, split: Similar to Insert Note at Mouse Cursor (using the I key), but positions new notes at the Edit Cursor. Inserts new notes (according to the current Snap values) wherever your mouse is hovering. These features work exactly as described on all selected MIDI notes.ДЄ very quick way to insert notes (using the Insert key).
