Civilization 3, you made two points I'll address:
1) The demand for notation/sequencing hybrid is reflected in Notion sales.
I disagree. If there was a DAW that kept notation and performance separate, similar to Notion in having a score in one hand, and a fine-tuned performance in another- and the notation was similar to what we are asking in it's integration with a sample library (more than Notion SLE, but how we've described)... then I think there would be more interest. Notion is a hybrid... but I didn't buy it and I'm all for the idea. I just don't think they did enough integration and enough work on making their hybrid style system into what people really want from the idea. I know other users online and in person that didn't go with Notion for that exact reason.
2) That VSL can't justify supporting such features, because of a lack of interest.
How many in the digital music world want notation composing with good sound? Count everyone in the Sibelius, Finale, Notion, VSL, EW, crowds, and more... who have tried to get both sides working together. How good Sibelius sounds are is a big deal to Sibelius users. How VSL works with Sibelius is certainly important to a respectable number of the VSL user-base. Maybe not the majority... but maybe because it simply hasn't been implemented very well so far
Consider this... When you write for a cello, you don't hand a cellist a piano-roll style print out of the score. You give them notation, why? It's the standard and what we are all most familiar with. So why would a digital cello be any different? Because notation doesn't serve performance in the way that computers will process and play it back to you. A piano roll is much more specific but less readable to people. Notation is more general and readable, but to strict to instruct a computer for good playback.
So I have two points 1) Can playback improve for the notation world? Yes, of course! It badly needs it. 2) If you could easily get the right cello performance out of notation, would you need the piano roll anymore? No. You wouldn't. Different users use notation, piano rolls, midi controllers, etc. But notation has suffered the worst in playback ability because of the nature of computers and how they only do what you tell them to do on a very basic level, etc. Why should this be of interest to VSL? Because VSL is an orchestral library. VSL would probably rather Sibelius get playback working in a VSL-friendly way... but as it is still far behind... users who prefer notation suffer from it. How many orchestral composers want notation? How many users do sample libraries loose because of their complexity and more 'sequencer-daw attitude'?
In the end, only VSL can really decide if it's in their interest... as I've stated on here. But pointing out the benefits and additional feature ideas to help this conceptual editor is certainly more than dreaming, it has it's productive benefits... If VSL does it... great! If they don't, then we've at least established a conversation online where VSL may reference later, or others may reference or find ideas that may still serve this purpose (in one way or another). So in the end, there is still a point in making certain problems and desired features aware. The more people talk about what they want from a product, the better... whether VSL develops it, or even if another hobbiest finds a way to help VSL users through other means or ideas. It's definately worth talking about. And the more users that chime in with their support... perhaps it will get attention.
And this isn't strictly a notation thread. I've just been replying frequently with Errikos about notation. You mentioned the Tempo track in Cubase. I wouldn't think that it's the most code-heavy feature of Cubase. (maybe I'm wrong, lol) VE really does have a lot of DAW features already. It has plenty of non-traditional DAW features also, that primarily only serve VSL users. Are there sequencing and editor features (both notation and otherwise) that could improve for VSL users alone? You bet!
