Code for exploring scales / microtonal tunings is now on GitHub
That's it really -- the link is at the top of the page (in the row of buttons above the banner). The code itself is a bit primitive and not as nice as my old Java code but it might be useful to someone. More importantly, perhaps, you'll find Scala files for all the microtonal tunings I create for this blog in convenient folder there. No more clunky Dropbox links that expire without warning!
