Despite the fact that many people have concerns about the GUI, especially the red colour - I find it pretty cool. It does provide what it is made for: It gives easy access to the sounds and effects. The sounds are mindblowing!!! Specially the guitars and the strings are very, very realistic and provide a very broad dynamic range. I think the sounds can easily compete with hardware ROM-plers like the Roland XV 5050 or even better. The only difference is that you have to pay several fold more for the hardware unit than for SS.
Features: SS does what it is designed for: In conjunction with the Sampletank LE engine it provides a huge, high-quality sound library; The Sampletank-effects are good and they allow to tweak the sounds by the means of EQ, delay, reverb and others. Unfortunatley you can not manipulate sounds on the sample-basis. But remember: This is a ROMPler - It is no sampler.
The documentation: is a little bit thin. I would appreciate a complete list of presets and a short description of each one.
Presets are excellent - no question.
Support - I think everything best that can be said about Squids and his Sonic reality suport have been said so far. I can only agree with that. At this point I have to also say that the KVR-Forum was very helpful for me.
Value for money: To date I think there is no concurrence for SS: Best bang for your bucks ratio ever seen so far.
Stability: This is a little problem: I needed 6 weeks to get SS run with Cakewalk Sonar. I tried everything: Diferent VST-DXi Wrappers, different operating systems, all possible combinations of mainboard / graphics card / sound card drivers and so on.. At last I got the right combination and now it is working. Once running I have not experienced any problems so far (But it is running just since 1 day;-).
One additional very positie point: Sampletank /SS comsumes much less CPU power than other samplers like VSampler or Halion or even LiveSynth Pro.
