unfortunately I get some unexpected behaviour of filtergraph (in
combination with the "selectfilter" - message)
I would like to build a multiband eq using filtergraph and cascade
therefor it would be very usefull to set the filter coefficients
(meaning freq, gain, Q, type) from outside,
which works fine when I use the mouse to select a filter, unfortunately
not when I select a filter with the "selectfilter" message.
maybe anybody knows how to do it properly, or is it just a bug?
