The Control Surface Integrator (CSI) is a Reaper plugin that aims to let you integrate your hardware control surfaces into Reaper with a much higher level of control than is possible out of the box. If you're prepared to put in the effort to customize your configuration, you will be able to integrate one or more MIDI, MCU, or OSC, control surfaces into a single virtual surface.

This wiki serves as the official documentation.

This started out as a wiki project by Malcolm Groves, but Funkybot is now the major contributor, with a little help from Geoff, the developer of CSI.

If you find something out of date, either comment to let us know. Comments, corrections, and additions are very welcome. Please provide feedback via the CSI Thread in the Reaper forums.

PC (64 bit), Mac (Catalina or later, including Apple Silicon), and Linux are supported.
