[Noisebridge-discuss] openeeg

[Vlad Spears]

I may have given the wrong impression to some with my remark about  
drum 'n' bass.  I've done some reading, Jonathan.  Yes, part of my  
interest is exactly what Meredith describes.  I'd also like to see if  
I can guide the parameters of generative musical apps in various slow  
moving ways.  I think filtering, compressing or limiting the data  
could provide interesting and usable control.

I'm quite happy with muscle movements as part of the event set, too,  
but my goals for excellence may not align with yours.
