[sdiy] Reducing maximum current through analog switches inASM-2ADSR

[David G. Dixon]

Why not just use a smaller cap at C401?  Ray Wilson's ADSR uses a 1K
resistor with a 1-uF cap for a minimum attack time of 1 ms (OK, 1.08 ms if
you count the on-resistance of the switch).  A 15-uF cap is switchable for
extra long times if desired, so there is no compromise on long attacks.
Even a 2.2-uF cap would allow a 470-ohm resistor at R405 for 27 mA peak
current and a minimum attack time of 1.2 ms.

Also, if, for some reason, the cap shorts (as I understand they are
sometimes prone to do), then there is the possibility that the peak current
becomes the steady-state current.  If this happens to be 167 mA, then this
will surely fry the switch, will it not?  It's cheaper to replace a cap then
a quad switch and a cap!
