Butter2ndHPF and Q control

As you know, I'm trying to recreate our specific tuning, to compare the voice performance to our MP units, and I've been struggling with the filters in AWE to match... It turns out that some of these filters don't let me change the Q factor. Specifically, the Butter2ndHPF that's found in the Biquad Cascade module. The really strange thing is that the controls for this filter are all visible - is this a bug? Should I be able to control the Q factor on this filter? Are there other filters like this that I need to watch out for, to avoid some more headaches?

Please advise if I need to send an AWD file to observe operation issues.

Hi Terry,

 

See this post for a discussion about the Butterworth filter: https://dspconcepts.com/forums/feature-requests-and-bug-reports/410-chan...

 

As is mentioned in the documentation for the Second Order Filter Smoothed module, not all the filter parameters are applicable to every filter type. For example, the gain filter type won't use the cutoff frequency or Q parameters, and Butterworth filters won't use the Q.
