Hey Stenzer,
What can I say, Marius pretty much hit it right on the spot. You have to understand that most patches from other companies are mathematically "perfect." That is to say that everything is tuned perfectly to concert pitch or A440 blah blah. Also, every interval from that is tuned with exact mathematical precision, which of course as stated above, does not give a realistic sound since no string players play with perfect mathematical pitch even 50% of the time-much less 100%. Also the recordings were done very "dry." This means that while some companies use extensive reverb to make up for realism, LASS gives you a realistic interpretation. Of course in a live recording/scenario there is the overtone series that you must take into account, which will create an infinite amount of "mixed" textures depending on the space size, decay, etc. Of course if there is a patch that sounds "out of tune" and you are not mixing it with any ensemble, just use the tuning feature on the patch itself. I'm just barely scratching the surface with what this program is capable of, but so far I am astounded at the realism and expression. Also, if you plan on using it-read the manual. I can't stress that enough. There are so many features on how to mix and match patches and advanced functions that could easily be overlooked. Anyways, I hope these reviews help you in your decision.
Happy Scoring!
