Hi, without some concrete (ie. maths + standards) information, it's not really possible to know what you are after. Is there a standard for such controls, or a technical description of how they work and exactly what they do ? Are they even standardised, or are they whatever the particular manufacturer dreams up ? It may be possible to provide some generic facility to help with such adjustments, but more information is needed on how it works, what the procedure is, and what the aim is. Graeme Gill.
