This really is pretty good. Ths sound is realistic compared to my SBLive so full marks on that level. While the CPU load is moderately heavy (which should really be improved) for the price I suppose you can't expect much more.
In fact the VFM is the only real issue I have with this VSTi. When you consider the price compared with the Virtual Sampler etc, it would be a lot better if it were multi-timbral. As it is so easy to use (and you don't need Sampling capabilities when using Soundfonts, that is what Vienna is for) for the money, if the thing was multitimbral, it would be a much better investment.
