MOTM

It seems to me I read something once about using multiple FWRs as
frequency doublers in envelope followers.  This is supposed to improve
the response time.  I may have read this somewhere in ElectroNotes, I'm
not sure.  I'm out of town at the present time and unable to verify the
source.  It might be interesting to have outputs from multiple FWRs on a
module such as this.

It may be a ways off, but there is a MOTM Envelope Follower in our
future, yes?  I did some searching of the archives to see if I could
determine any info on this "elusive" device. :)  Not much luck, I'm
afraid.  All I could find was, that Paul indicated he was either going
to go with a more "standard" design, or a totally "over-the-top" design.
I sure what ever he chooses, it will kick a@@.  In any case, I am
wondering, what functions should this module include?

Obvious features would include rudimentary preamp, signal input, input
gain, gate output, gate threshold control, response time control,
envelope out and envelope level.

Some addl. potential features might be:
mic vs line level input
separate attack and decay response settings
trigger out
gate led
clip led
preamp out
FWR out
peak-correction circuitry (to enhance performance for even-harmonic
signals) multiple FWR/peak-correction AC-coupled stages

Any thoughts out there?

George
