Because of their long, curvy waveforms, low frequencies experience phase attenuation more profoundly than other areas of the spectrum. You may want to high-pass your square wave so that it gives the bass line that extra grit without stepping on the feet of your sine’s big clear lows. Additionally, many producers like to make low-end seem fatter by using stereo widening effects. Use these carefully as the phase interactions between the low end of each stereo side can cause destructive interference. Use the mono/stereo switch on your DAW’s master track to check whether your low end survives when everything’s running through the center channel.
We actually started from scratch! Victor and I are both music and vinyl lovers, but we always lived our passion in our private spheres. We had never worked in the music industry before and didn’t have many contacts in the music scene, to be honest. We had to build our own relations [and] convince and prove to some already well-established labels and institutions that our solution might interest them!
