I am in the process of incorporating preset management in my vst synth. I have reviewed and incorporated the designs found in the example projects supplied in the vst sdk. I am able to create and save presets and program lists, however I have no means to differentiate between loading and saving a preset vs. a program bank. Can someone point me in the correct direction regarding the interfaces to be used for this purpose?
I also need advice on which interface calls I need to inform the host regarding program changes selected inside the custom GUI editor in order for the host to reflect the newly selected program name, and any related information.
