[sdiy] Distributing CV Gate and Trigger

[Ray Wilson]

Here is a thought...

Use some TL084 or equivalent hi impedance op-amps in a non-inverting unity
gain voltage follower mode. Tie the signal you wish to distribute to the
non-inverting inputs of three op-amps and for each of those amps just short
its inverting input to its output (to get unity gain). Tie a 1K resistor to
each output and voila you are distributing 3 "good enough" replicas of your
original signal. Power the amps from the unit's plus and minus power supply.

Do this for each signal you wish to distribute.
