>I do get a lot of errors saying that it can't find the dsp process , and or that a new version of CDP is coming out and the process can't be executed
Your screenshot shows a message which comes up when there's a CDP error. Some of these can be rather obscure, but they're mostly down to incorrect parameter settings. When they occur, they are beyond the scope of Soundshaper and derive from the underlying CDP software. Your settings of a frequency split at 500Hz should normally be OK. (I've just tested it with a stereo input, with no problems.) I'm not aware of specific problems with Accumulate; however, if you want to send me the details of the sound source and parameter values used, I'll be happy to look into it.
I'm sorry you've had the inconvenience of not being able to access the forthcoming CDP8 processes yet, but unfortunately CDP8 is not quite ready for general release. In a further release of Soundshaper (6.03), which should out any day now, menu items which lead to a CDP8 process have been disabled. (A tiny number of CD8 functions, which are implemented as modes of an existing process, may still generate the message you quote, however.)
Regarding the tutorial - clearly these things are written at different times by different authors and the descriptions can unfortunately become a little outdated. The CDP Distort suite deals with wavesets (as described in the documentation and help screens) and it was felt that this menu title better reflected the waveset functions as a whole. We do try to keep the documentation up to date, though, and thank you for pointing out this discrepancy.
