Getting Started with Reaper’s MIDI Editor

To access the MIDI editor in Reaper, simply double-click on a MIDI item in your project timeline. This opens the MIDI editor window, where you can view and manipulate your MIDI data with precision.

Creating and Editing Complex Arrangements

Reaper’s MIDI editor excels at handling complex arrangements. You can stack multiple MIDI tracks, edit velocity, and automate parameters for dynamic performances. Use the piano roll view to see note pitches clearly and arrange your parts effectively.

Using Multiple Takes and Layers

Import or record multiple MIDI takes to layer sounds. You can then comp these takes by selecting the best notes from each layer, creating a polished performance.

Quantization and Humanization

Utilize the quantize feature to correct timing issues or humanize your MIDI data for a more natural feel. Adjust note timing and velocity to add expressiveness.

Advanced Editing Techniques

For intricate arrangements, Reaper offers advanced tools like MIDI CC editing, velocity curves, and scripting. These features allow for detailed control over your MIDI data, enabling complex and expressive compositions.

Editing MIDI CC Data

MIDI Continuous Controllers (CC) can be edited directly within the MIDI editor. Draw automation curves or manually input values to shape your sound parameters precisely.

Scripting and Custom Actions

Reaper supports scripting for automating repetitive tasks and creating custom workflows. Use ReaScript or actions to streamline your editing process and achieve complex arrangements efficiently.
