longer notes

[eridanishi]

The experimental page has instructions on how with the google javascript console ( Ctrl+Shift+J ) : http://onlinesequencer.net/experiments - if you're too lazy to look yourself, here it is.
You can do some hacky stuff using the Chrome JavaScript console. Type 

Code:

grid=(1/4)/(1/3)

 to change the grid size to whatever you want, where 1/3 is the new note length.

I am a chrome user so I have no idea how this functions on anything besides chrome, so if you use firefox or something, you'll probably need to figure it out yourself.
