I read the Audicle paper (ICMC 2004). Sounds cool! I wonder how you display the six-sided cube on a screen or do you use 6 screens for performances? Are 3D interfaces (on 2D screens) expedient for computer music? (i'm a little bit sceptical) Did I understand it correctly, that there is one dsp-server that renders the audio in a networked setup with several people/computers? does this mean that one can bog down the dsp-server with a resource hungry patch?

The idea is to be able to fully engage one face at a time, but you can move to other faces at will.

Some of the face will be 2D, others 3D, and also there is the tabula-rasa face where the user can display anything (2D or 3D). 3D can be effective for a lot of things, but can be bad if everything was conformed to be in 3D. Hopefully having both the 3D and the 2D will be an effective combination. We shall all soon see.

The simplest setup is the one-server/listener, in which case misbehaving code can hang the server. However, the model can include a conductor (using the on-the-fly programming / code as instrument idea), who can remove/fix bad shreds, and also the musicians/ChucKists can learn to play well together, which would also fit this model. Multi-server setup will also be possible, though we still haven't worked out the timing semantics. Best, Ge!

so you can switch between the faces on your screen?

:-) I never did anything with OpenGL. Do mobility video cards in recent notebooks support OpenGL in hardware? (ATI 9200, 9600, etc).

it gets complicated, when you try to synchronize different sound cards with own master clocks, but a ChucK rendering farm with a sound card in one of the machines would be cool! (I don't know if we have machines that fast enough to do any kind of sound processing in a few years, but i doubt it with third and fourth order ambisonics or 320 channels WFS, etc).

Yep. There is a command line that you can bring up (and hide) from where you can change to another face (using code or UI). Also there are keyboard shortcuts.

The vast majority of recent notebooks (in the last 3 years) support all the basic rendering in hardware for things the Audicle needs to do.

This is an intriguing idea - especially since we have a large research group here at Princeton doing shared high performance computing with very low latency (Kai Li's shared virtual memory, and the Princeton display wall - synchronized 24 cpu). This could very well lend itself to this. Also, we can use multiple hosts, and use network to synchronize or to otherwise compensate for the different clocks on the sounds cards. Best, Ge!
