Greetings,
       I wish to produce a wave form with the opposite form of the normal ead~ wave (the curves become exponentially steeper instead of flatter), which I can achieve by entering a negative number into the phasor in hard off's exact-ead~ patch, which I downloaded from the archive.  However, I still want to be able to independently change the length of the ascent, decline, and distance between waves as is possible with ead~.  Does anyone know how I could do this, or possibly have access to an abstraction-version of ead~?

Best regards,
Stephan
