Hi Paul,
Thanks very much for the quick reply but I don't understand the mechanism -
the host must be somewhat in control of it?
Digital Performer has a preset menu on the plugin frame and within this
there is a 'Save Settings' option. On one plugin that I have (an amp sim),
when I click on this, a dialogue appears to select the name/location of the
preset to be saved. On other plugins (including my own and all the MOTU ones
that came with DP), no such dialogue appears. I'm trying to figure out why
this is the case. You mention being asked for a filename - do you mean some
call into the plugin that asks for this?
I have implemented SaveState() and RestoreState() within my AU and I just
expected this to be called from the host with a buffer in which to save the
preset info to.
Thanks,
John.

Hi,
I'm new here and looking for information on saving an AU plugin user
preset.
I'm using DP7 as a host. If I load my plugin to a track and I click on
the
"Save Settings .." menu, I would expect a dialog to appear to allow me to
select where to save to. However nothing appears. I've noticed this
behaviour is the same for many other AU plugins, however some plugins do
seem to allow me to save settings to a preset file.
AU preset saving is handled by CoreAudio and not by the host. The
presets are in a standard format and are usable by all AU hosts via
mechanisms offered in the CoreAudio API. as a result, no individual
host gets to decide their format or where to put them. this is why you
can use presets you created in logic with mixbus or DP or .....
what is the flow when you get asked for a filename?
