If I understand Paul's logic, the graph is supposed to show the combined effect of all stages, so band 1 not being used should therefore have no effect on the resultant curve. Also, it's quite likely that when I first created the instrument patches I originally had some other effect in the first slot, but later decided it was better without it.
Something I find rather puzzling is the route taken to develop the curves. Parameters are carried through several stages to finally get to AnalogFilter, which itself contains all the filter types. Would it not be simpler to maintain a (possibly cut down) copy of AnalogFilter in the GUI code which can be linked to directly from the EQ controls. The compiled size of this is just under 20k, so not big by today's standards. -- Will J Godfrey {apparently now an 'elderly'} _______________________________________________ Yoshimi-devel mailing list Yoshimi-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/yoshimi-devel
