NOTE: This extension has been superceeded by the built in grouping functionality of Reaper itself. This page is only kept around for historical purposes.
reaper_grouping.dll (Drop into your Program Files\Reaper\Plugins directory.)
This is a REAPER extension plugin that adds mix groups (VCA) functionality.
Open the grouping dialog from the Reaper View menu "Show Groups." Right click in the dialog for commands, or right click tracks and select Mix Groups.
This forum thread is currently the "official" place for documentation, bug reports, feature requests, and new version announcements.
Quick start:
Select some tracks that you want to group together; maybe all of your vocal tracks. Right click on one of the tracks, select Mix Groups->Make group from selected tracks. Now anytime you select, or change vol/pan/mute/solo, they will be linked.
There is a known incompatibility with MCU-type control surfaces, sorry.
NOTE: The download link below is just the file URL, so that's it's possible for me to update the utility without redoing this ReaperStash entry. Left-click and pick open, or use the "reaper_grouping.dll" link above, as opposed to downloading the .URL file.
