The Interactive Soundscapes project is about creating soundscapes intuitively. Samples can be loaded, simple effects can be added, and then the sounds can be mixed in the soundfield. Not as advanced as Tapestrea, but it seems to work very elegantly.
Jon Olav Eikenes has posted information about his diploma project on control of sound spatialisation at the department of interaction design at the Oslo School of Architecture and Design. As a co-adviser I think it is great to see an interdisciplinary project working so well. I hope we can get more of this type of collaborative projects in the future.
The AudioPint project at MIT aims at creating a computer based system that is as portable and stable as hardware gear:
Consider a system that is small, lightweight, tough, able to be powered up, plugged in, and it used immediately – but with sounds that can be controlled by any computer-compatible input device, opening wide the space of expressive possibilities. Devices supported include midi controllers, joysticks, mice, touchpads, or any other custom controller that can connect to a computer!
The AudioPint vision is to build a portable, durable, and inexpensive sound synthesis and effects system that is based completely on free open-source software, is flexibly reconfigurable and easy to use, and that is capable of accepting a diverse range of input devices for control purposes.
It reminds a little about the idea behind PLORK, although this is taking it one step furter.
Came across the web site of MIT course MAS.960 Principles of Electronic Music Controllers, which has some interesting references and links tovarious resources on NIME development. It is also worth checking out many of the student projects.
