Yepp everything is true, but to find the average is not how music works. For me it is a challenge to cover a rich song with only 4 channels. You have to improvise and look for solutions. You can shoot tones from both pulse channel in a way that it sounds nearly like a full chord. You can hear this in many of my tracks. But 4 sure there are songs you cant transcripe. Like I said, besides of the wrong tune, your game has damn potential. And I offer myself as a musician & composer for future projects or even would help out with the current one, if you like. That said, I wont bother you anymore with that.
