I recently updated to Samplitude Pro X4. When I click "Solo" on a track it doesn't completely mute the other tracks, it just lowers the volume of them a little. I'm guessing this is in settings somewhere, but I haven't been able to find it. I tried changing the "Global solo modes" on the master fader (since search showed me a post about that working) but that didn't help. What is Solo "supposed to" be set to if I right-click the S-button?
