When I first got this library, I was pretty stoked to hear some sounds that were quite usable for what I was trying to do. After using it for some time now, that has very much worn off and I am pretty sad that I paid $300 for this. About ninety percent of the sounds are horror soundtrack stuff, so much of it is dismal and dark. There is virtually no customization of the sounds, no ADSR for amp or filter (major setback). Most of the sounds I do like are more like chords, so I am not able to use them tonally as I would like. I want to decide for myself if the sound is going to be used in a major or minor key, not have the sound decide for me. On top of that, I have found that some sounds seem to be quite out of tune, or at least don't fit in as they should when I play the root note of the key I am in. Maybe I am spoiled from Atmosphere, but man, I feel like I paid $300 for maybe ten usable sounds that I can't customize really at all. The delay, phaser and reverb are almost useless as they are sent pre-filter (can be a cool effect, but I don't like being restricted in this way). Also- the instrument loop stuff can not be changed with tempo independent of pitch, so the tempo of my song will dictate the key, if I can even get it to line up right timing wise. Seriously disapointed.
