Rebuilding the ADSR curve after Distortion

[amptramp]

I had an idea at one time to design a pedal that used SCR's (silicon controlled rectifiers) to generate fuzz harmonics by dropping the signal to zero after the signal had reached its peak.  If you use a peak detector to regenerate the ADSR waveform, all the information is there because the signal peaks are there.  It is possible to generate a distortion that generates new harmonics but allows the ADSR information to be retained.  In fact, it would incorporate a peak detector made of a sample-and-hold to prevent the SCR from triggering before the waveform had reached its peak but permit the declining part of the wave to be chopped out.  This would give you a distortion that generates a new sound without interfering with the ability to recover the envelope at all.
