VCADSR - 3510

VCADSR

It's a little more expensive but the 3510
vcadsr is much more capable than the
standard adsr. The 3508 has been a
favorite through the years and we keep it
around because it is a simple, useful,
inexpensive circuit.

VCRADSR

Although not part of this kit it's easy to put
the rate parameter back on. Simply
remove R12 and 13 and connect a 50K
voltage control pot to the loose end of
R11. I even put a pad on the board.
