Before Templates and Presets, we used Import Song Data for this purpose. I kept a "song" as a Template holder. Open it and Import to it to save, Import to another song from it to retrieve.If you could manage to be able to save several tracks with the midi that would be awesome though..
Like, you could get rid of everyone's unfinished projects and just have them in an ideas folder..
Maybe it's not possible, but it would be so handy..
