With due respect to the people that have been trashing AI in this thread, I would like to offer a counterpoint perspective.
I should stipulate that I agree that the demo on the AI site does not sound as good in many ways as polished final mixes from VSL or EWQL. However, I believe that many of the commentators are missing the point of what AI is trying to do- create a process for a very quick and realistic rendering of orchestral compositions. I do not think they are trying to equal the overall sound quality of an EW or VSL product, but are instead trying to address simplifying the orchestral recording process and add more musical spontaneity. I think it would be interesting to compare a real-time (no overdub, no editing) piece on VSL or EWQL to AI. Perhaps someone on the forum can post something for comparison.
Now, as far as the price is concerned, let's compare the hardware requirements of setting up a real-time equivalent EWQL or VSL system to the cost of AI. I think one would need multiple computers for trying to do what AI can do (eg. multiple articulations real-time) in the same way that AI does. So from that perspective, the price differential between AI and other systems to set up a "real time" composing situation probably isn't that different.
Additionally, even though others may be able to engineer the DVZ and time hysteresis elements, AI is leading the way in introducing these technologies and should be applauded for advancing the state of the art.
I followed the blog trashing of VSL for years before they launched and eventually refined their product to its current state. They were ahead of their time and suffered through similar negative commentary, only to later prove the nay-sayers wrong. My observation of the end-user community of musicians is that many often fail to truly appreciate the efforts of developers to advance the state of the art, developers whose efforts are often motivated more by passion for the art than desire for monetary reward.
I am not affiliated with AI in any way. I am only reacting to what I have been reading on this site (and others) and commentfing about what I understand about the intent of AI. I, for one, applaud the efforts of AI for what they are trying to accomplish. I hope they can succeed, because musicians and composers will benefit as a result.
