@Armando-Consuegra You can technically record in stereo and then manually split the recorded stereo audio object into two mono audio objects, which you can place on two separate tracks.

But Music Maker can't record on more than one track at a time. It's deliberately limited in this regard. You would need Samplitude Music Studio for multi-track recording. Samplitude Music Studio is now published by BorisFX and no longer by Magix.
