The reverb that this ORB7000 plugin creates is very rich and adjustable. There are many parameters to set and change. There are of course the regular parameters for a reverb, the pre-delay, damping, room size, width, dry/wet mix make the foundation for the reverbration. The amplification parameters allow for a volume-wise differently timed and shaped reverbration ramping. The filter section comes with low- and high pass filter for the reverbrated sound. The reverbration generated on an octave below, the original octave and an octave above - adjustable in level for each octave - allows to enhance sound in a way that differs from regular reverbs.
The now released version (first version) of the ORB7000 doesn't work as good as the "personal" version I received after mailing with support of 123Creative, who created an excellent plugin with what it seems a buggy protection mechanism on top which crashes on multiple instances of the released ORB7000.
So, if you purchase the plugin, you could experience crashes, which for me was solved by their support by sending me a "personal" version. I hope they will fix this bug in the future. I had no problem with the purchase and downloading and registration.
So, it's actually an excellent plugin if the developers get it to work completely, or when you receive their working version.. (as on 2013dec17)
