Channels can be panned Left to Right by dragging the Pan slider. Zrythm supports Linear Pan, Square Root Pan and Sine Law Pan, with a Pan Law of -6dB, -3dB, or 0dB.
These settings are configurable through the Preferences window. The default is Sine Law with -3dB. If you don’t understand what these mean, it’s best to leave them to their default values.
