I love the limitations. As you all know there are never limitations in terms of the music style or feeling one might want to create. I'm talking purely systematic and hardware limitations. I just like knowing that I'm never very far away from reaching the bleeding edge of what the hardware is capable of. It's better for my learning and better for my creativity. I innovate and think creatively cause the system forces me too. And when I finally do finish a song I'm pleased with, it makes me all the more proud that I made my happy chip friend in my console sound amazing despite the incredible limitations that it my have.
^A thousand times this. Pushing myself and the tracker to its limits is something I do on a regular basis. Always entertaining and a good challenge (I've made entire tracks with one generator and one channel just to see if I could do it). I still marvel at some of the clever ways chiptune artists make it sound like they have 5+ channels to work with.
