I am intrigued. As a dedicated SD3 user, it would have to be very good to compete with SD3. I am, however, an enthusiastic user of the Modo Bass, which I got at a great promo price in the early days of it's launch. I also have other physically modeled instruments I love, such as Pianoteq and AAS Lounge Lizard, for examples. Physically modeled virtual instruments have a couple of advantages over sampled VST's. One is the smaller footprint and faster load times. The other, more importantly, is that a physical model simulates real world playing better than samples. A recorded sample is just that, a recording that cannot be altered, just processed. However, a physically modeled instrument can predict variations in performance on the fly and provide greater variety of articulations, in that a human being will never hit the keys/drums/cymbals/guitar/bass strings the same each time, and will vary the articulation either purposefully or randomly. Samples w round-robin are great, too, but still limited; and I believe (not absolutely sure of this) that the variations are virtually limitless in a physically modeled instrument. Mathematics algorithms are used to produce the variations (if your arm is getting fatigued you might hit the strings with less force or at a different angle, for example). It sounds crazy, but I believe it is the future of VST's. I will always use and enjoy both types of virtual instruments, but MODO bass convinced me that IK can do the job well enough to risk the expenditure (it would be $150 for me as a MODO bass user). Still mulling it over, and don't know when the actual release is scheduled, but I'm inclined to give this a whirl.
