Reply to Looking for specific plugin

I have noticed that some soft synth plugins have a graphical ADSR envelope. I am a newb and this is great for me to see how specific values create the curve. Many of the free VST synths I have do not feature a graphical representation of the envelope. Is there a free VST plugin that shows a graphical x/y axis of ADSR envelopes that I can chain to my various synths.
