Fantastic Daniel - good luck with everything. Here's what I would find very interesting, a full integration of the notation features of The New Thing with Steinberg's Cubase / Nuendo, using all of the playback (midi and audio) features of Cubase, such, that notes in The New Thing can be manipulated simultaneously in Cubase (including automation, plugins, and tweaking of midi notes with expression etc). That would allow a much greater control over the audio output than is currently possible in Sibelius and would make the transition between computer music and printed music for live recording and performance much smoother. By tapping into the existing technology of Steinberg you could save yourself a lot of time, and Steinberg would have the edge on everything else out there.
