Hello to all,

Happy New Year!

Some 20 years after designing it, I have finally got around to adding 
pvx support to the CDP system - "Release 8" is now on github as a Beta 
source release (all LGPL). This means that pvx files are no longer 
confined to Csound.

see: https://github.com/ComposersDesktop/CDP8

This is still very much work in progress, so expect changes and random 
updates - we are still in many cases trying to understand many of Trevor 
Wishart's new programs (over 80 of them at the last count), so 
documentation as such will be a while yet. We may exclude some currently 
listed, and maybe add others even if a bit "experimental". But we hope 
practised developers will have a go.   As fits a beta release, we need 
testers who can report bugs etc. The full system is now over 220 
programs. I have full builds available for PC and Mac, so anyone who 
really wants to dive in but not build from source can email me offlist 
to get links. We are still some way off making a full "Release" with 
install packages and documentation etc.

We use MinGW for (32bit) PC builds, and CMake as the build environment 
on all platforms - all thanks to John Fitch for setting that all up and 
checking builds on Linux. I have yet to do the same for CDP8, so some of 
the CMakeLists.txt files may not be quite right yet.

I have also posted a small repository just for PVOCEX-related things, 
which may interest those making more than occasional use of pvx files:

see: https://github.com/ComposersDesktop/PVXTOOLS

This includes small zips (Mac/PC) of a few programs: the "pvocex2" 
program I did way back when (can make a stereo analysis file), and a few 
CDP workhorse utilities such as "dirsf" which will print to the console 
a list of soundfiles in the current directory, with format information - 
now including pvx files, so you can see quickly what format any pvx file 
is in - window size, overlap, duration etc. Of course it handles 
standard AIFF and WAV files too. "pvocex2" also has a flag option to 
report format information.

Also "pvplay", a (command-line) program to play analysis files, with 
lots of options;
and "specvu", which will print the amp/freq values of a requested 
analysis frame to a text file. The full program set has other tools for 
reporting analysis information - rarely just one way of doing things.

We also plan to start creating some libraries of CDP processes, minus 
the considerable (and somewhat obscure) overhead of "Soundloom", 
Trevor's highly original but-not-always-obvious GUI front-end (but 
already handles all the new programs). Any programmers interested to 
join in will be most welcome.
