Question about Pro-Q4: auditioning/solo mode on a low cut filter
Moving up or down when auditioning will only change the gain when you use a shape that actually has a gain function. Since HPF/LPF filters don't have a gain you can not adjust their volume while auditioning.

Hi there, I'm evaluating Pro-Q4.
When in solo/audition mode on a low cut filter, moving the mouse up/down doesn't seem to adjust listening level as it does when auditioning bell or bandpass filters. The tooltip and manual claims that it does. Am I missing something?
