Pro-q 3 works fine, but when everything is idle overnight or idle throughout the day whilst I go to the day job, the output goes very quiet or nothing at all.
the GUI stays as it should be which is the last changes I did.
Got 2 workarounds
1. move the EQ points away and back to the same place, and one of them will get it working
2. duplicate its instance in Ableton live and delete what you duplicated from.
video of doing workaround 2:
Ableton live 10.1.9 (not tried laptop yet with 10.1.13)
i7 7700, 24gb ram, plenty of solid state drive space.
