This is another project of mine, Compose. (I just typoed "Compost", so I think it'll be the official name now.)
It is VAGUELY (

leftClick: toggle a square [on/off]
rightClick: toggle a square [start/stop]
m: toggle mode [sine/kick.ogg]
up/down arrow keys: increase/decrease tempo and reset time
space: pause
The notes are written to the left of the grid(I don't think they should be written like this, but whatever) and two red lines show you the current position.
If you have any suggestion or question, feel free to ask

EDIT: Added the possibility to create a longer note, right-click a square to toggle it between start and stop of a note (start is green, stop is red)
