I run Filterverse on its own track with an Orchestral Tools track as its sidechain. Every time I restart that project, which has no other tracks, everything seems to work fine, but there’s no sound coming through. When I disable Filterverse and unmute the Orchestral Tools track, though, it plays fine. What I need to do to make it work again is remove the Filterverse plugin from its track, then add it back and then it just works until the next LPX restart with that project.
