I have been a user of =FILTER= since the DOS days and I wonder if there is a way to quickly do the following:
To REPLACE/CONVERT all CAPQ models with a better model using just a command after a filter is synthesised.
eg I previously create my own more detailed model for a cap using series L series C and Q etc and the 'new' command replaces all the caps in the default synthesis with my new custom model (using default values for stray L and Q etc that I specify. I could even make the defaults frequency sensitive with an equation).
The same for the inductorQ models in the default synthesis.
At present I have to do all this manually which takes time on high order filters. If the bandwidth or stopband alters after this (it always does...) and I need to add an extra order to the filter than I have to start again and mod all the Caps and Inductors to the better model manually.

Great idea! Seems like this could be implemented two ways. Since the number of different components used by the various synthesis modules is limited to resistors, inductors, and capacitors (lines are already handled using advanced T/Line), the most convenient method would be to allow model selection within synthesis. One complication would be that multiple and user defined parameters would need to be handled in the synthesis module.
An alternative method, which would be handy for situations other than synthesis, would be to allow selection of multiple components and switching the model for all of them, much like making multiple parts tunable is handled now.
