I've been calling zero for a 5 second long buffer filled with various samples. If I run the program with the buffer already full there are a few seconds of nothing - the panel windows CPU % etc doesn't kick in - I suppose while SC crunches its way through each sample, and then it prints the list and panel window comes to life. If I call zero from a GUI button then everything stops in a similar way until it prints the list and once again comes to life. (In such cases I have altered zero in as much as it doesn't have arguments) So first question is am I asking too much in terms of processing ? The other question is - why does the Mac often freeze ie never return from this limbo it seems to go into when zero is called ? Could it be that some buffers have too many zero points ?

It can be driven by a score, or operate in real-time on Power Macintosh computers under graphical, mouse, or MIDI control. SuperCollider can also be used for algorithmic composition with real-time synthesis or for real-time effects processing. The system contains its own interface builder. CREATE is sponsoring a weekend tutorial and conference on Sound Synthesis and Processing with SuperCollider. The program will begin with an optional tutorial day on Friday 27 February, taught by Stephen T. Pope and based on his book "Sound and Music Processing in SuperCollider." Saturday and Sunday sessions (28 February and 1 March) will feature presentations by CREATE staff as well as contributed papers. Ample opportunity for exchange of information will be provided, and computers will be available for demonstrations. The special invited guest is James McCartney, inventor of the SuperCollider program. Mr. McCartney will speak about the history of SuperCollider, plans for its future evolution, and will field questions about SuperCollider techniques. We invite participation by attendees and presenters. Please send abstracts on any topic related to synthesis and sound processing with SuperCollider, including: musical applications, synthesis techniques, graphics and sound, control strategies, algorithmic composition, novel interfaces, and pedagogical applications. We will accept abstracts by email, fax, or the post. ---The deadline for abstracts to be received is Friday 9 January 1998--- Notification of acceptance will be sent via email within two weeks of the deadline. Those interested in participating as attendees (not presenters) should contact us to register and receive an information pack. Registration at the door will be accepted.

Before I tried a lot with a 5300. Certainly you get much more performance out of the 3400.

I use SC on a PowerBook 1400cs that has a NuPowr 183 MHz PPC 603 processor upgrade and 28 MB of RAM. It runs great! stp _ Stephen Travis Pope _ Center for Research in Electronic Art Technology (CREATE) _ Department of Music, Univ. of California, Santa Barbara (UCSB) _ stp@create.ucsb.edu, http://www.create.ucsb.edu/~stp/
