bip all

I ben using vbap for manny yers in the ambiunix system, its a multi  
speaker setup for live performances and R/D, the first yers it was  
based on max/msp but when there came a hardcore c programmer in to  
the project we ported the all to carma/linux and the last weeks to  
stable debian/linux, sorry maxers, just better sound, on hdsp  
hardware, one mistake i remember vas to  make the panner go from 360  
to 1 -continue the cirkel, is that the problem?

going to put more info on ambiunix.dk, for nu only old stuf on http:// 
ambiunix.komponent.dk alle software is free, just mail me.

They are listed there as pd extenrals also, try it out.  If there is
source, it's usually pretty easy to port Max externals to Pd.  There
are some ambi ones there too.

There are also ambisonic externals from IEM and Jasch, for better
spatialization.
