Well it´s not a tracker, it plays tracker format songs (xm, mod, it etc). it´s a great littlte program if you wanna listen to all those classic computer songs. There are thousands and thousands of them to download for free. But the sound is a bit weak, would be great to see som sort of EQ in mikplayer.
A simple tracker program would be great to have for the GP32, like a portable ministudio to have on the road. The input of notes would be a problem but it could be solved with a smart layout.
