I got full version of Serum, fresh install from Splice ( and I didn't use Serum Fx, just Serum VST), made a sound according to your tutorial, but suddenly after I made it, Serum stopped producing a sound. it shows wave signal, and lfo cutoff matrix signal works and all, but there is no sound. Even if I reset it to init settings, default or use another preset, still nothing. Any clues?
