I downloaded the demo of QL spaces and was very impressed.
It has a streamlined interface, simple controls and suggested presets for what you might want to use it on. Much more detail in the reverb compared to what is included in the reverbs that are included with the Play libraries such as Symphonic Orchestra, even though some share the same names, they are much more “realistic” sounding. Also, it is very light on ASIO usage.
I had to buy it.
