I really am close to having most things covered. Adding the Arturia V collection in their end of year sale added a couple of long lusted after synths. developers are going to have to come up with something special now. A lottery win would have me chasing hardware, mainly a Synthesizers.com modular.
Drums.I will add Drumcore 4 lite to better utalise my Kitcore content but I think, for the moment at least, I have enough drums. So far I have even passed on The Nick Mason kit for BFD.
Synths.I might be tempted by GForce's Oddity if it went 64 bit and was on sale, but I need to dig deeper into Reactor and the recently acquired Arturia synths before buying more. I would not mind upgrading my XLS3 LE to the full version but IMHO the upgrade is overpriced even before you add in the cost of the dongle.
Samplers and Libraries.Sampletank 3. well lets see what it offers and what the upgrade price is. It will need to be a) Cheap or b) really bring something to the party.
Kontakt - I expect we will see Kontakt 6 and Komplete 10, again it will depend what's new.
As for libraries I would be tempted by an "Irish" bazouki or Mandocello from some one like Bolder sounds with similar features to their Mandolin. A Rikenbacker 12 string electric from Orange tree would be a dead cert as would a Strummaker 4 version of Indignus Torch.
Maybe Kirk Hunter Spotlight Strings if the Group buy hits 50% off, but I will need thinking about.
Of course Hollow Sun and Hideaway are bound to come up with something unique and cheap enough to buy on impulse.
Effects.I got it covered, I have more compressors, EQs, delays, saturation, channel strips etc. than I know what to do with. that said new Pro Channel modules may be my downfall.
And finallySonar X4?
