I would aggree with this, yet take precaution to know for sure that a
person has limited aural skills developed. Personally the use of the ear
when doing ETD assisted tunings is becomeing one of my pet peeves. The more
I dink around with these things, the more I see potential and or real
threats to the ear. Course that said I also see real and potential
benifits.

just me on this list who is on about this buisness of multi-partial
displays.. could we expound a bit on this ??
