the “example-3-busses” shows how to open a GUI and manipulate effects like low pass filter , band pass filter, peak limiter, etc
but these values do not get saved; i.e. after closing and opening the app the settings are gone.
i know i could read each value out and re-set them as per the “examples-4-paramter”
via printParameterList() and AudioUnitSetParameter().
but maybe there is an easier way ?
