#2What is "cyberphysical coding"? I didn't see any definition on the website, and no, I haven't seen any live examples of it either. It sounds cool, but from looking at this site, I have no idea what they are talking about.

#4I had a chance to sit down with Mr Sorensen some years back and talk PL design.
I can easily recommend Extempore (xtlang) especially if you're a bit more advanced programmer. The underlying core is a tasteful mix of C-aligned semantics (think LLVM) that manifests as S-expressions with the usual goodies. It is statically typed with inference.
Another forte is scheduling via temporal recursion.
It has a solid memory allocation strategy, via memory arenas, oriented to high performance and low latency. Higher level constructs like closures can live in arenas. You can also introduce some custom dynamic cleanup routines for RAII-like behavior.
I seriously think it could work well outside of its niche as well.

#5There used to be an emacs/lisp library that did this, does anyone remember the name ?
Re: Extempore – An audiovisual live programming environment
#6I’ve tried several live audio programming languages (though not to any great extent), and have found Extempore to be easily the best. It’s the only language I’ve found which lets me control both the low-level details of synthesis and the high-level details of musical structure, and — more importantly — edit them both live. The low-level language is C-like and statically typed with all the advantages that brings, and as a Haskeller I find it intuitive to structure the high-level details around recursion (in Scheme in this case). My only real frustration with it is the lack of documentation, though the source seems pretty readable. (That, and the fact I haven’t found anything to use it for yet!)

Have you tried out the ChucK language? I haven't tried Extempore yet, but it looks like the way they handle timing could be similar. ChucK has a very elegant system for synchronizing synthesizers and sequencers where you can write code in a simple imperative style (within a sequencer you can "wait" until the next note needs to be played). The language runtime keeps all of the coroutines running in sync with a global clock. I don't know of other languages that use this style of timing, so I'd be very curious to hear how they compare.

#9I've had the pleasure of watching Andrew Sorensen perform with Extempore multiple times. The improvisational and creative musical capability of Extempore is astonishing.
