As far as future module thoughts, something I'm finding myself needing is
something that outputs a voltage based on how fast an input voltage changes,
then the output voltage drops back to zero when the input stops changing. It's
kind of like an AC detector, getting rid of the DC component. I'm needing it to
detect the initial breath of air from a breath controller and also to eliminate
the DC portion of the output of my Spacebeam. If anybody ever does a module
like this, let me know. I'm trying to think of a way to do it on the current
MOTM module line. Maybe I can go through the AC portion of the mixer or
something.
