it would be great if in lmms added support midi as main format for project (coz it;s common standart)
I am talking about not just import/export
I am talking about save own projects in midi-files, maybe with some project extra data (such info about rhythm pattern, used sound vst plugins and etc).
or maybe that extra info will saved at end of midi file or some separated file with project preferences (and then I would prefer a text format for that separated file).
