red band upper L corner of solo button

[may4th]

Hi All,
In two vocal tracks of a piece I've been working on have a red band in the upper left hand corner of the solo buttons. I've never seen this before and have looked in a bunch of Reaper books. but have yet to find what it means. Anyone know?
Thanks.

In the "view" menu, open the "track grouping matrix".
I think you have grouped these tracks, and the solo is slave.

Something like this ? (colors may differ)



That's track grouping. You can connect several buttons or faders to operate from one for example.
Should be described in the user manual under 'track grouping' in detail (I guess).

If that's not it, maybe post a screenshot.

Thanks guys. They were grouped together. How that happened I don't know but I was able to fix it in the grouping matrix. Thanks for the help.
