They have a tape (cassette) with the demo on it. The demo also includes a swept tone passed through the filter. A comparison of the sound with and without the filter is given. The effect of the filter is extremely noticeable, however CBS contends that the filter used did not comply to their specifications (a likely story). The HRCC's address if you don't already have it is: Home Recording Rights Coaltion P.O. Box 33576 1145 19th Street N.W. Washington, D.C. 20033 Has anyone thought that there might be an alternative motive behind CBS copy code? I doubt that the record companies are losing as much as they say they are. I think their additional motives may be is to kill DAT for two possible reasons: (1) They have invested alot of money in CD pressing plants and don't want competition from DAT's (2) A DAT machine allows a musician to make high quality tapes without the need for CBS to produce him/her.
