First of all I was hoping there would be a NATIVE tracker on the Kindle.
Second, I tried the gameboy emulator because I am already familiar with using LSDJ (tracker) on authentic hardware. Emulation is also an option for those that don't have real hardware.
Third, I am not trying to re-invent the wheel here. I don't plan to write any music programs I just wanted to know if there was anything already available. I posted the examples of other trackers running on 'non-standard' hardware for creating music just to show that people do develop this sort of stuff.
Like I said, it would be cool if I could use the Kindle to MAKE music, but if not, I will move on. Plenty of other devices/communities out there
