For quite a while there is musical software out there which helps you in generating music – no I am not talking about software like Reason or oldskool software like ScreamTracker or FastTracker. The software I am talking about works by displaying a matrix of blocks which you can press independently of each other. The whole matrix of blocks is usually being traversed horizontally from left to right by an imaginary reader. By pressing a block a tone is being generated when the reader passes the block. By combining multiple pressed blocks you can make spacy music.
I have seen several of these programs on the internet already and today I found another very simple and tiny online music generator, but this one has a nice 3D presentation. Go and try it yourself here.
