REAPER's Routing Matrix is a one stop window for managing a project's entire routing needs.: you can add and delete sends and receives and manage their parameter controls. Alt R opens the routing matrix. For the file All Through The Night with Bus it should be similar to that shown here. Observe the cell in the matrix where the Gtr Body row intersects with the FX Bus column. It contains two small blobs.Right click over this cell to display controls which determine how the signal from the Gtr Body track is sent to the FX Bus (see above).

REAPER’s Routing Matrix default display of paired outputs might include several that you do not want. You might want to only “natural” pairs (e.g. 1/2 for your speakers, 3/4 for a headphone amp). Non-standard pairs like 2/3 can be removed using Options, Preferences, Audio. Turn off Show non-standard stereo channel pairs .
