[sdiy] Distributing CV Gate and Trigger

I thought that you were going to send outputs from one sequencer to multiple points...

If you are trying to combine the OUTPUTS of sequencer gates and triggers, you need to
"or" them together. Diodes will work fine... but remember that a high level will dominate.
If you try to "or" gates together, a long gate from one sequencer will hide a shorter gate.
Triggers will do the same, but since they are short, you will probably not notice...

A wierd thing to try might be to exclusive-or the gates together...

in my original reply... I meant to say that one gate could drive many output jacks at the same time...
you might rather call that a "multiple" or "mult"...
