Did you double click the piano track in the BIAB VST ?
it can be confusing as some users think yellow is solo color,
blue is sync play, green is mute and red is mute,
I thought green was go and red was stop but both green and red are stop, I got confused at the traffic lights the other day after using BIAB VST I pressed the brake twice with my left foot thinking the lights would turn blue and I could go I think I was just still a bit stressed out crazy
EDIT: in the pic I should of set the audio send to none.
