[sdiy] Diode/Led/Gate out question

Guys/Gals,


I'm just about to finish this sequencer I've been working on for the last
week.  I'm at the 'wire all those pots and jacks to the PCBAs' stage.  I
have a quesion for you guys which would a save me from wiring yet another 9
pin Molex connector, of which there are already 5 ( I have a lot going on on
the faceplate):

I need the outputs of the counter to do three things:  1) create the voltage
for the step pots 2) step gate outputs and 3) step LEDS.  I have the output
of the counter coming to the faceplate in two ways: A) straight from the
counter itself and B) counter outs routed throuh a non-inverting buffer just
in case i need more 'umph'.  I figured I would wait until I start playing
with it to see which needs to go where.

I was planning on just running the outputs of the counter (either buffered
or not) through 1n4148's to create the gate outs. But I also them going to
eight more diodes, thr step LEDs.  Could I take the gate outs from them
instead? From (after) the LEDs?  will that suffice my needs?  In the
billlion or so sequencer schemo's i
ve seen I've never seen it done like this,  but I am curious if it would
work.

let me know and thanks.

Peter
