i tried out Markleford's "key peddler" MFX plugin, and im not sure if im using it correctly.....cause i really dont notice a differnce in sound or playing when i use it.

in the plugin, it has a "key finder"....and you can assign the key to activate this plugin (im assuming)....so it hit this button, and hit a key on my keyboard, and it assigns that key to trigger this 'vertual pedal'............

but is i play the sounds (vioals, pianos, woodwinds, etc etc)....and hit this trigger key and continue to play....i dont hear any noticable differnce in sound/playing dynamics at all........

am i using this thing correctly?
