How do I change the location to look for the license file per product? about rs-met

[RobinSchmidt]

presets or license files? because these two types of files are handled by different classes. the license check is handled by the class PaywareAudioPlugIn (in your shared folder). preset files are handled by my AudioModule class. that's a kind of lower level "pseudo-plugin" class that handles presets, parameters, states, etc. but an AudioModule can be simply wrapped into a plugin (payware or not) by the call (i use the TestPlugin as example):

AudioProcessor* JUCE_CALLTYPE createPluginFilter()
{
  TestAudioModule *dummy = nullptr; 
  //return createPluginWithMidi(dummy);
  return createPaywarePlugin(dummy, TESTPLUGIN, 3);
}

you could introduce a juce::String member variable in the class PaywareAudioPlugIn and set it up like:

AudioProcessor* JUCE_CALLTYPE createPluginFilter()
{
  TestAudioModule *dummy = nullptr; 
  AudioPlugin* plugin = createPaywarePlugin(dummy, TESTPLUGIN, 3);
  plugin->setLicenseDirectory([insert license file directory string here]);
  return plugin;
}

you would then also have to implement the function setLicenseDirectory which should...well...do the obviuos thing (set the corresponding member variable)...and then use that string in the key-checking function

presets on the other hand are handled by the AudioModule class, which all of your products are subclases of (and then later get "wrapped" into an actual plugin). somewhere in the constructor you have: setActiveDirectory(getApplicationDirectory() + "/TestPlugin");. you would just need to replace this call to change the (default) preset directory

by the way, the purpose of this AudioModule/AudioPlugin wrapping business is to be able to combine several "Modules" into a single "Plugin" (without having all the host/plugin communication overhead in each module) - like a filter is a module which can be used inside a synth plugin project - but also be wrapped into a plugin by itself - if one so wishes.

...it also enables hierarchical preset management which is a cool thing for more complex plugins. ...load/save preset for the filter, osc-section, envelope-settings separately, etc.

...wait no... that plugin->setLicenseDirectory won't work because at this time it might be too late to set it. i have to think about that

ok, as soon as you can, tell me how I could customize the license directory per operating system per product
