Pro-Q (Q factor)
As I understand it, Pro-Q 2 and Pro-Q 3 both map the standard 0.707 Q to 1.000.
In other words, a Q-factor of 0.7071 in many other EQs maps to a Q-factor of 1.000 in Pro-Q 2 and Pro-Q 3.
I'm wondering what the possibility might be of introducing a toggle switch so it can display a 0.7071-based reading instead of 1.000 mapped reading?
I understand it might be a lot more complicated than this, as different EQs have different shaped curves, so it may be difficult to program in such a swtich...
Just an idea anyway. Thanks for reading.

Hi Jim,
In Pro-Q we did not want to use the overly technical "0.7071" value, as most plug-in users have no clue what this strange value actually means and why it would be chosen as default. That's why we've simply chosen 1.0 as default.
And indeed, for Bell filters, just multiplying with 0.7071 gives you the 'traditional' Q value. For Shelving filters, the mapping is a bit more complex though...
We're not going to add a switch for this unfortunately... sorry :-)
Thanks for the reply Floris.
No worries about not adding it. I can understand why you've designed it this way. It must be a fairly complex thing to implement, so no worries about keeping it the way it is.
Many thanks again.
