Hi Dave. Don't worry--you have time to get to a Linux machine as the interface and effects in the demo have not been released yet. What's described in the documentation has been in Non Mixer for 5 years or so. Documenting the recent changes is still on my TODO list. That being said, currently the new interface shares the property of the old in only representing the top hemisphere. I've played around with multiple views to allow manipulation of negative elevation, but I decided that it was too confusing for the user, especially considering A) the extremely small number of people with periphonic rigs and B) the even smaller number of *musical* scenarios where a sound source should emanate from below the listener. Still, during that demo, most of the time the crow was actually below the horizon due to the fact that I automated its flight path rather carelessly by clicking the mouse at random points on a Control Sequence in Non Timeline (and the automation input is not bound by the top-only constraint that the interface is). If you care to share your use-case for negative elevations--I'm ready and willing to be convinced of their utility. I was just planning to ignore the issue until such time as I reimplement the interface using OpenGL--where the ability to move the camera and display more visual cues to its orientation would make manipulating points over the entire sphere more usable. Although the demo video shows the source positions being automated, that is not actually a very likely use case IMHO. It was merely done to highlight the effect. The actual use case is positioning instruments on a stage (such as an orchestra). _______________________________________________ Sursound mailing list [email protected] https://mail.music.vt.edu/mailman/listinfo/sursound
