ive had problems with no sound from some tracks in a project.
ive found that on the tracks this is happening, the LC and HC in the pre sections has bugged out. the knobs are all green with no stripe indicating its position and i cant turn them.
what ive done to “solve this” is to create an automation of LC and HC in the arrange window. i can then set LC and HC to a “real value” and sound is restored, i can then turn off the automation and use the knobs again.
