Implemented Divide "Supply Sag" into "Power Amp on/off" and "Supply Sag Amount"

[km 202257]

First of all, I sincerely appreciate Fractal Audio's hard work for customer support and product development always.
While I'm a fully satisfied owner, I'd be happier if you could consider my request detailed in the following:

• Functionality in question
  • "Supply Sag" control in Amp block, that controls both on/off of power amp simulation and the amount of supply sag
    
• Requested change
  • Divide the control into the following:
    • "Power Amp on/off", that only controls whether power amp simulation is engaged or not
    • "Supply Sag Amount", that only controls the amount of supply sag
  • * The proposed parameter name is just an idea and can be named as whatever FAS prefers
    
• Problems to solve by the requested change
  • Those who tweak around the "Supply Sag" (including me,) accidentally hit the bottom of the parameter "P.A. OFF", leading to:
    • surprise, and risk of hearing damage due to a sudden increase of volume
    • risk of damage to a PA system or other equipment after the AXE-FX due to a sudden output increase

+1 very organized post. I've always wondered why this isn't two separate controls already.

I had asked the question as to why sag and p.a. on/off are co-located in the same control - see discussion here - still don't really understand why P.A. on/off is not a separate switch.

Thank you for sharing, I should have searched for the past forum posts more carefully.
That said, I'd still like to keep this thread open as I guess the possible risk of damages I mentioned has not been discussed before. The core of my request is to have sort of a "foolproof" mechanism to mitigate such risks.

Definitely! - My odd brain patterns really want that control to be separated out

I see no technical reason to not implement this. It's simply changing how the UI behaves: Limit the knob to a value one notch above "poweramp off" and add a switch that toggles this setting to 0 (poweramp off) or whatever value is set on the knob.

if (isPowerampEnabled == true) {
   supplySag = supplySagKnobValue;
} else {
   supplySag = 0;
}

If this is done, it would be great to add a modifier to Supply Sag Amount parameter.

I could do some wicked stuff with that.

Scared the crap out of myself the other day. Just meant to tweak it slightly, but the mouse knob motion turned it off completely. LOUD!

Implemented.

Thank you for the implementation, all the FAS team.
