Are you interested with the 1-bit audio for this system?
It's pretty nice to have others like you to contribute, making chiptunes!
Working for advanced audio in this system might be pretty troublesome, but I had wrote a bit of helpers to make audio programming for this system easy :D
I will post a tutorial on how to produce music for this system here...
You may head up here (XO-Tracker), and see what the XO-CHIP's sound system is capable of.
