[sdiy] LFO inertia

[Ken Stone]

use a basic lag circuit.  VC into a resistor into an electro that is
grounded at the other end. output from the juntion of the two parts. To have
separate increas/decrease rates, use two resistors eacn in series with a
diode in place of the single resistor. Diodes face the opposite way of course.
