Thanks, Urs. I was hoping to avoid the development time to write a
translator, but if I have to, I have to. Do you know where I can find
the AUPreset format sepcification? I've been looking around in my
Developer doc's for a while now, as well as the ADC site, but I just
can't seem to find how the contents of the <data/> section of that xml
file is spec'd (as written out by Logic 7, at least).
Thanks,
Howard

Hiya,
I really do not understand this request... what's the problem?
So, you do have .fxp or .fxb files? - These are (more or less) well
documented formats:
http://www.steinberg.net/steinberg/ygrabit/vstsdk/OnlineDoc/vstsdk2.3/
html/plug/others.html
The .aupreset file format is documented as well (it's a plain XML
PropertyList...)
The final structure of each preset format depends on how the plugin
handles persistence. If your plugin does not handle persistence in its
own proprietary manner, both .fxp ( float params[] ) and .aupreset
(<data> key) just store an array of floating point numbers, one for
each parameter.
If your AU parameters are just as normalized as your vst parameters,
you can just copy the array from one preset format into the other
(using CFData for the .aupreset, of course). Otherwise you will have
to calibrate them.
Anyways, a batch preset converter should be *very* easy to write,
regardless if command line utility, Carbon application, droplet,
php/perl script whatsoever.
Cheers,
;) Urs

Hi again,
we desperately need to convert a large number of factory presets to
work with Audio Units. Has noone come across this problem before?
I'm not sure which would be quicker at this point... writing my own
converter or manually creating all those presets. Obviously, a
conversion utility would be the most helpful. Is there no utility
out there to do this for me? (Doesn't matter if it's from MAS, VST
or ProTools format...as long as I can end up with .AUPreset format.)
Thanks,
Howard
