silly idea - add scales?

[Chrisedmo]

Hi Alex, I was going to try and fork this and try and add in an option to only play notes from a certain scale? Like the little kaossilator does?

I gave up though as i'm not really a javascript guy (which i was though!) I was looking at something like this: https://github.com/GregJ/music.js what do you think?

Would love to have this as a feature :-)
