Yes, I don't blame you, though Spitfire Brass Pro will be launched fully this coming week - I'd already done that some months ago because I owned the library and was using it myself, so 75% of the work was done. I had to thoroughly test it, create the templates, and do a lot of extra work on the underlying patches, and create the plugin to do the microphone configuration. That thing has just under 300 custom patches, so if you need to change one thing (like a controller assignment), you've got 300 things to manually change, and Kontakt doesn't do shortcuts!
I will actually be launching quite a few sound sets next week, and I've got my Windows dev certificate so I can sign my code now. The work recently has gone into upgrading the installer and testing it with various kinds of sound set - namely (a) non-kontakt player (such as BBC Discover), (b) kontakt player with numeric library id (Action Strikes), (c) kontakt player with problematic library id (Spitfire Brass), and (d) a library that needs full Kontakt retail (Glory Days Horns) - the challenge with (c) and (d) is making them autoload by cheating. It's a long story. The installer also needed to be upgraded to support a playback configuration merge utility - which allows you to combine libraries in a mix-and-match way. So basically, by challenging my installer with different kinds of libraries I had already created sound sets for over the last few years, I was able to make it flexible enough to not need too much changing in the months ahead. It's an installer that can now install multiple sound sets into multiple installations of Sibelius at once, for instance: and when it delivers patches to Kontakt, it searches out the library, creates the directories, and also creates pointers if necessary so that it just works without any batch resaves.
With the BBC sound set, I had to wait until Spitfire had their current 50% sale to buy the Pro version because no one's giving me these libraries and BBC wasn't one that I owned - I had hoped pre-orders would help buy it, but that didn't really pan out because there were relatively few orders in the soft launch. So in this whole venture I'm still quite in the red financially. I hope my faith in the Sibelius community to support this is going to be vindicated.
Anyway, so I have BBC Pro now and it's next in the queue, and will be started this week. Much of it is quite similar to Spitfire Brass/Spitfire Strings Pro in available articulations. I will finish Core first, and then move onto Pro. I imagine that it will be a couple of weeks before Pro is launched. Honestly, it's the patch alteration and drum maps in Sibelius that take most of the time!
After that, I will do Spitfire Strings Pro, because again I already owned it and used it. I'm trying to cover as many genre bases and vendors as possible, and have some exciting ideas about delivering curated collections of sound sets in one hit for specific genres: like Big Band, where if you have Glory Days Horns, you're still missing flutes, clarinets, a double bass and percussion which can be patched in from other libraries and vendors - including some of the excellent free/cheap instruments currently available in Sinus or SoundPaint.
I hope that's enough detail about the plans!
