ENSONIQ DP/4+ (Input Envelope Follower)

[TechnoManiac]

Is it possible in some way to assign an “Input Envelope Follower” in ENSONIQ DP/4+ as a modulation source? I need me to modulate any parameter depending on the level of the incoming signal. For example, in Korg A1 or Lexicon LXP -15, this is called - "Input Envelope Follower". Among the possible source of modulation in DP4+ I did not find anything similar. Maybe I missed something, or maybe it can be realized somehow differently? For example, through the input CV.
