Generally wondering about their stuff and anyone here who has used, what you thought about whatever you used etc.
I had bought Strawberry and Stratosphere and both sounded excellent but then Orange Tree totally screwed up the GUI. They used to have the whole guitar so you could see the pick direction and then decided to cut that out and just focus on the fretboard which was really an odd choice since the fretboard display is so laughably inaccurate on which notes are being played in what position and how the chords are fretted that it boggled my mind as to why they would focus on the fretboard and do away with the pick direction.
Typical developer stuff...two steps forward, one step back. What else is new.
The good thing that came out of all this is that the change was so annoying I just decided to learn guitar and stop using guitar libraries. After a developer makes a bad decision and you lose faith, you start thinking, "Who know how many more bad decisions are coming. Do I really want to be chained to more of this developer's bad decisions?" Normally I would have switched to a different sample company, but I honestly feel that the Orange Tree guitar libraries were the best out there already so since I lost faith in them and there was no other developers to switch to, that's kind of what made me think that if you don't want to hitch your wagon to more bad decisions, the next step is just to learn the instrument.
I figured out something along the way - an electric guitar, even played badly already sounds better than a sample library. Orange Tree libraries I still think are at the top when it comes to guitar libraries but even Strawberry and Stratosphere has a lot of weird resonances I was always EQ'ing out to get a usable sound. The first time I threw a mic on a guitar amp and just recorded, it was eye opening. It already sounded better than the two libraries I had with virtually no effort. Even played badly, the libraries couldn't compete tone wise.
I get that this isn't an option for everyone and I also acknowledge that I have an advantage as I already make a living as a session musician (piano / keys) and so the only other people I know are really session cats and so when I decided to learn guitar, basically in exchange for a pizza and a six pack I got lessons from some of the best guitarists on the planet (And exchanged some piano lessons for them as well!)
But if you're already a musician, it's not impossible to pick up guitar. Within 3 months of woodshedding I could pretty much play whatever I needed and within 6 months I was gigging on guitar and actually picking up work.
The guitar libraries (or at least the two I have) sounded great and like I said are probably at the top of the heap when it comes to sample library guitars. So if you pick them up, you won't be disappointed.
In the end, I honestly have to thank Orange Tree because if they didn't screw up their GUI, I would have still been using the libraries (and most likely dumped a ton on more because all of their guitar libraries would have been ones I needed) but instead I actually ended up ditching the libraries and learning a new skill that not only opened my ears, but has made me income. The money I would have spent on their libraries instead I invested on real instruments and that's probably for the better.
Seriously though - anyone on the fence of a sample library, try throwing a mic on a real instrument and play it (even badly) and I guarantee you, it'll be eye opening. It just might be the thing to push you to learn a new instrument!
