http://www.beepbox.co/EDIT - To play, you need to click to make notes. Its like Midi Sequencer, but better
There are 4 instruments, 3 I don't know, but grey is drum. You can set things with the extras
on the side, example "i don't want it on easy mode, set it to expert" good now you can use all lines
or other cool stuff...oh and you can link directly to your beepbox.
ayway lets get beeping!!
