annotate plugin/DSSIPluginFactory.cpp @ 60:3086ff194ea0

* More structural work on feature extraction plugin C <-> C++ adapter * Allow use of LADSPA/DSSI plugins with control outputs as feature extraction plugins (DSSI with MIDI output still to come) * Reorder labels on spectrogram status box * Minor tweaks in doc etc.
