What is the output of the gate jack look like? Is it a pulse once
every cycle, and the rest of the time it's 0V? If that's the case, why
would you need a mixer to mix them together? It seems like you could
just go from the gate out jack to the switch, switch to a common
output. Unless each of those needed some sort of buffer to mix
together? The LED should protect the chip from voltage from other
channels getting back to the chip, I assume. You might need an
additional diode to sum them together so that the pulse signal doesn't
confuse the length switch. Otherwise, you might use the mixer/inverter:

These could all mix down to the inverted output jack, and you could
use another module when you need an inverted out.
