It sounds wonderful in the demos. Vienna Symphonic has other free instruments (since there's a plural on the free instruments. Just wanted to comment on the Win version that will automatically restart your computer, but you get a warning to go back and save your work if you have things open. Be ready to check cancel. I think it may time out after a few seconds. I always have stuff open it big projects to keep track of what I'm working on. The ilok license platform has easy instructions. Vienna has an assistant that you have to download and install and it will take care of the download. When you install it, that's when it tries to restart your computer.
Unfortunately I found the installation a little bit complicated. It was not clear to me, that I had to install the Vienna Synchron Player first, after having installed it and the library also, first nothing happened, until I realized, that I had to activate the library within the iLok License Manager manually before it is recognized.
I have a lot of iLocked plugins and almost all others open a window for activation at first use automatically, so I did not expect this procedure. Now I know it maybe for another installation in the future.
Once installed and activated the library works well and sounds very convincing. Comparable large file size for a single instrument, but ok, on the other hand this one seems to be a very unique library of a beautiful, very naturally sounding instrument and the sound quality also is excellent.
I've never heard of this flute before, but it sounds interesting, beautiful and seems to allow a lot of vivid modulations, in some way it sounds to me like a mixture between a regular (bass) flute, a pan flute, an American Native flute and a didgeridoo, due to the special overtones, it can produce.
Underrated instrument, as far as I can hear.
A handpan library in the same quality would be the perfect complement to this instrument in my opinion.
