I understand Logic 7 is a proprietary process. I also said the chip was programmable- therefore a company could (might) use the chip to decode its proprietary DSP. Hey, I could be wrong! I believe I have seen it mentioned on the Cirrus web site that they have worked with Logic 7 or have the capability to decode same. Some consider the DSP chip to be the "engine" in the processor unit. My origial post was really intended to compliment the Outlaws for using a DSP that Lexicon felt was worthy enough to use in their unit costing 10 times as much! Sorry for the confusion. Thanks for your replies!
