is there a way to trigger an effect or a effect parameter via on/off on my midi keyboard. Logic 7.2 user here.

I figured out out to trigger an effect with the keyboard.

Hi K1, It's great when you figure stuff out! Would be great if you could post your solution too ;-) Cheers Rounik

I figured it out kinda, but I figured it out backwards. it goes wet when I release the key and dry when I press the key. I'm looking to do just the opposite.

cool. So have you built an environment to do this or are you doing this another way?

arrange window, and the controller assignments window. Instead of turning a knob for automation I pressed a key on my midi keyboard. But it's backwards.

Hi K1, Can't remember if this is available in L7... in the Controller assignments window under "Value" see if you can change the "mode" to "toggle". Can you post a picture of your controller assignments window here. Also, which plug-in are you assigning the key to, and which parameter is it? Bypass? It's usually better to use a button in my experience as keys deal with note on / note off values. Cheers Rounik
