Because it would appear that whilst it is okay to change “must copy the hardware” from mono to stereo, surround users do not matter. After all, we were promised when the Surround Edition was withdrawn that we would get an even better replacement. I’m still waiting, years later, and suspect I will still be waiting in a few more years. One of the main reasons I put off going to 64-bit for so long is simply that I am going to lose probably 75% of my surround tools when I make the jump next week (new system finally ordered) including the LFE Splitter/Combiner (these just crash W7), all my Starplugs (not only have they gone under, but they do not work in W7 reliably and as they are now gone thanks to some bastard uploading cracks of their entire range it is not going to happen either), the TonyB tools and many more - even my sole Waves bundle - and old 360 surround one. If I want it on the new rig I will have to buy it again in effect - which I will not be doing as it was not very good in the first place.
(sigh)
What else do we have - the Flux suites. I did try these once and was underwhelmed to be honest (control was not what I was expecting it to be as operation at the time was multi-mono with a matrix for channel control (similar to the VirSyn tools) and to my way of thinking, multi mono is unacceptable.
The best currently available for my money has to be the Voxengo stuff. Aleksey has donethese really well, allowing independent control over the groups and there are 4 of these that are user definable. MUCH better.
It is a real shame these Porticos are stereo/mono only. Obviously surround users do not matter.
