I just wanted to say what a true joy the Garritan products are. I started with purchasing Personal Orchestra 4, then Classic Pipe Organs, and most recently World Instruments.
I've been entering public domain scores (e.g. Vivaldi, Bach) into a music notation program (MagicScore Maestro), exporting this to MIDI files, and then using the Garritan libraries with FL Studio to create my audios.
Unfortunately, I wasted money by purchasing sound fonts for another product (who will remain unnamed); I found the freely available sound fonts to be better quality than the those in the commercial product that I wasted $150.00 on.
But then I took a chance on Garritan. Oh - the joy!!! I literally feel like I'm conducting a real orchestra when I listen to my audios. From the manuals alone you can see that the Garritan products are an act of love, from musicians and for musicians.
For Christmas, I had given one of my best friends a recording I made of Vivaldi's The Four Seasons (his favorite). That recording was made with free sound fonts. Then I gave him another CD, this time with the recording made with my Garritan libraries; he thought I had spliced in clips from a real orchestra!
I just wanted to share this with others.
