I’m a bit disappointed - I had high hopes for ST 4 based on the size and sound spectrum of its library. Unfortunately, it’s not very CPU-friendly for a sample player - the effects on the individual sounds seem to drive up CPU load, but even a simple electric bass patch - with all effects REMOVED - will generate a 10% Cantabile load on my system (quad-core i7, pretty modern) without even a single note played!
I had hoped that using a sample-based VSTi would lighten the load compared to the virtual synths, but in that I was disappointed…
Plus, there’s still a number of teething problems with the software and the sounds downloads (zip files ending prematurely, installers not installing the libraries correctly until you run them a second time, patches being displayed multiple times…) in their current shape, So far I fail to get excited by ST 4. Guess I’ll stay with my current arsenal for live usage.
