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.
Is it possible that some plugins use the SaveState() method to throw
up a file dialog in an attempt to override the AU preset mechanism? If
this is true then you'd expect to see the dialog when saving a session
too I imagine.

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?
