Switching wah wah effect on and off with maximum volume

[bigalminal]

I’m using the Kuassa wah wah plugin with my digital guitar through a standard volume pedal and an Audiofront adapter. I’d like to be able to switch the wah effect on and off by using maximum pedal as you do with a real pedal. I’m not sure how to do this. Can someone help me out here please? Many thanks.

This is a version which activates the wah effect when the volume pedal is higher than 0.

@David-san

Yes, this is doable with a GPScript. But, there is a slightly different solution which doesn’t require any scripting. The idea is that if your pedal is at 0 the plugin is bypassed, if not it is active.
To do so, you can:

• use a pedal widget together with a led button
• assign the pedal to the wah parameter of the plugin
• assign the led button to the bypass parameter of the plugin
• assign both widgets to the same widget group
• invert the led button value and modify its max range to 2.0.

This is done in the following gigfile (the associated plugin is a MIDI in block, only to illustrate the principle): wah_and_bypass.gig (6.1 KB)

It could be modified to do what you want. But perhaps you could also use it as it is?

Here’s a rackspace script someone posted the other day. I played around with it and it works fairly good.

var
wahsw : Widget //wah on/off button
Slider2 : Widget //wah pedal

On WidgetValueChanged(newValue : double) from Slider2

if newValue == 1
    then
	if (GetWidgetValue(wahsw) == 0) then
		SetWidgetValue(wahsw, 1)
		else
		SetWidgetValue(wahsw, 0)
    	end
end

End

Depending on your pedal you may need to make some value adjustments.

i used to use one like what david-san posted and if you use a range of 98-100 instead of 0-2 it should work. but i came up with the bit of script above and it works great for me. i might switch back to the scriptless version though, just to clean my kind of crazy rackspace scripts up a bit…

David-San; I used your version. Works great. Thanks very much.
