Muse

Z - add/erase notes | select options in the menu X - change instrument hold X - back to menu Just put some notes on the grid to get a feel for it. You can save your songs to the cart itself, and I guess also share your crazy creations as cartridges here using that option:). There is also a demo song in there if you want to check out one of mine (disclaimer: not a musician by far, listen at your own risk). Have fun! All comments, suggestions and ideas much appreciated :).
