Here is the question: In standalone mode, PT has the option to map midi controls to next/prev instrument and next/prev preset. Unfortunately it doesn't seem to provide those options in plugin mode to the host (mainstage in this case).

Does anyone know of a way how to do that? Preset switching is nearly instant in PT, so there really isn't any need in keeping a complete PT instance for each instrument / preset. Would be better if I fill the ram just with sample based instruments that need to be loaded.
