Reaper OSC Action

This plugin allows you to trigger actions in Reaper by specifying the Command ID of the action. Unlike keyboard shortcuts, it lets you execute actions even when Reaper isn't in the foreground. For example, if you're recording a podcast and browsing the web, you can easily set a chapter marker by pressing a button on your StreamDeck without interrupting your workflow.

This is also helpful if you're running out of keyboard shortcuts. Since every action in Reaper, including user-created ones, gets a unique Command ID, you'll never run out of options to map actions to StreamDeck buttons.

Additionally, you can specify IP addresses or hostnames (including mDNS hostnames like mylaptop.local) to send commands across your local network. You can even send commands to broadcast or multicast addresses to control multiple Reaper instances on different computers.

Added the option to send commands to the MIDI editor of Reaper

When creating a new Action Button an additional drop down menu allows you to select the command target, e.g. Main / MIDI Editor

Note: The MIDI Editor needs to have window focus to receive command id's. This is a limitation of Reaper.
