Dimension Pro Proteus Expansion Pack, anyone have opinions?

Try a PM to timswartz (qv) to get answers to the factual questions.  Ethical considerations may prevent him from voicing opinions about the subjective questions, however.

I have the hardware Proteus 2000 (paid about $800 new) and bought the complete set (DSF Proteus Pack) when Cakewalk offered it for $300. The sounds of the Dim Pro Proteus2K are identical to the hardware. It sounds to me like they used the same (original) waves in the software.

I don't think you'd regret buying any of those packs, although a bundle sale would make it a better buy. I also like the PX-7 drum pack because it has tons of kits, most of which are GM mapped.

You can't tweak the sound parameters like in the original hardware, but you can use Dim Pro's controls to control filter, eq, etc. of the entire sound.

Thanks for the info and the link I'll check out the link you posted.  I'm hearing some positive things from other people which definitely makes me interested. 

As I mentioned earlier I don't think the web page for the Proteus packs is doing a good job selling the product because it only has a few sounds and it's kind of confusing as some of the demo sound names appear in more than one pack.  The web page for DimPro has many more sounds and it was very easy for me to understand and I have to tell you it was the DimPro web pages that made me buy the software.   I went through and listened to all of the demo sounds at a loud volume and it sold me on the product.
