Intro to Live Programming with Overtone

[Sam Aaron]

Hey there,

you may have heard about Overtone - the Clojure front-end to SuperCollider server that we've been working on for the past year or so. However, perhaps you've not seen much of it - and if not perhaps you'd like to?

Well, I've just finished putting together a very short (4 min) fast-paced introduction to Live Programming with Overtone, or you might think of it as How to Hack Clojure to make Music :-)

(This video also serves to demo the Live Coding Emacs Config https://github.com/overtone/live-coding-emacs)

Overtone really looks awesome, looking forward to use it! Thanks for the video.

Wow, that is awesome, I am definitely going to have to play with that.  As a side note, what did you write or use to configure your emacs in that way?

Thanks :-) Hopefully we'll see you on the Overtone mailing list somepoint soon...

Actually, the effects are a bit of a cheat - I added them to the video using Final Cut Express. However, it would be awesome if there was a terminal that offered this kind of glow effect. The closest I've seen is Cathode on OS X (http://www.secretgeometry.com/apps/cathode/) but that's a bit too heavy on the visual effects, and it doesn't run fancy terminal apps like emacs particularly well.

You can get similar effects with highlight tail mode in emacs. The elisp in there might give you some ideas on how to get some of the glow effects.

reich-score is really impressive. Looking forward to playing with the new features.

Happy Hacking,

Oh nice, I hadn't seen highlight tail mode before. I do use eval-sexp-fu.el (http://www.emacswiki.org/emacs/EvalSexpFu) to fade the currently evaluated sexp in and out which is a similar kind of trick. The glow effect I was referring to as the Final Cut Express fx is the persistent shine you see on all the text which makes it look like a retro games console.

Do you mean the Reich technique or the ascii-art? The ascii-art was hand-crafted and assigned to a snippet shortcut (reich-score). I used yasnippet (http://www.emacswiki.org/emacs/Yasnippet) and the following snippet text https://github.com/overtone/live-coding-emacs/blob/master/etc/snippets/clojure-mode/reich-score

If anyone else has any tips on how to make your Emacs look fun and fancy - particularly in the context of using it as a presentation tool, I'd love to hear them!
