I have picked it up somewhere but I'm not exactly > sure where. what you're discussing is not only about latency. i respectfully ask that you read this blog post and then follow the links to the original paper: http://createdigitalmusic.com/2008/12/intimate-control-multi-touch-new-models-and-what-2009-is-really-about/ if your pad is only a trigger, its not so relevant, but if its providing more than just a trigger then randy's ideas are really important, i think. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
