Based on some posts in this forum, I've decided I'm going to take a closer look at Notion 6.
1) I've already found that they have better support for artic-maps for certain 3rd party VIs, and thanks to Andi's research ^^, this currently includes VSL Special Editions 1-4. Would love to see them support VSL's full VIs, even if one-by-one!
2) I've felt that, in any notation program, the quality of sound of the VIs and expressive potential and realism of the instruments can actually inspire the creative process and the desire to compose, and can influence the direction and orchestration of a work. Perhaps some other notation programs have underestimated this??
This personal experience I found echoed elsewhere, e.g. in a quote by J.J. Abrams (Star Wars: The Force Awakens, Star Trek, Lost) "If you're lucky, the tools themselves will inspire you..." . NB: He was speaking of composing with VIs, software, ..compositional 'tools generically' (I presume) and, to be fair, not specifically about VSL. Nonethless I feel the principle applies more broadly to top-of-class VIs in most compositional work, especially within notation software and in writing for orchestral instruments.
4) Presonus (who make Notion) also make a powerful DAW: Studio One which is Rewired to Notion 6. Whilst it may not be a perfect dovetailing of the two yet, at least they're trying to support and streamline composers' workflows, as well as offering (?increasing) support for sophisticated 3rd party orchestral VIs for Notion (through their own time and investment), such as those made by VSL.
5) Even if a program might lack some features of other notation programs, yet if they devote their own in-house dev-time to support high-quality 3rd party VIs more than their competition, then imho they might win over more interest. And customers? Especially if they also escalate the sophistication and competitiveness of their notation software. If they do offer more in-program support for 3rd party VI artics & samples, then perhaps VSL might reciprocate this support in their VIs?? ..A win-win..
Feedback/experience/suggestions from others would be most welcome..
Cheers,
A
