Converting Gate to Switched Trigger (S-Trigger)

Converting Gate to Switched Trigger (S-Trigger)

2011-07-06 by hajimmie

Hi,

I'd like to play DarkEngergy via my MS20 so I made a cable like this: http://www.doepfer.de/faq/gen_faq.htm#S-Trig

On the test, when I connect: external SEQ Gate -> MS20 Trigger-IN, the gate signal triggers correctly (was inverted with a normal cable). But if I connect MS20 Trigger-OUT -> DE's Gate IN, no signal is coming from the cable I made.

Can somebody suggest if I am likely wrongly made the cable or, I need a different wiring scheme in the sleeve, and if latter how?

Thanks in advance,

Hello,

the cable you describe converts only from V-Gate to S-Trigger, but not 
the other way around.

A S-Trigger to Gate converter looks a little different. As example check

http://www.xmission.com/~dingebre/Trigger_Converter_4x12_1.1.pdf

The circuit in the most left row is the Gate->S-Trigger as you know it 
from the Doepfer page.
The circuit in the second row is S-Trigger->Gate

As you can see, you need supply voltage for this. So the best advice is 
to build this circuit either as additional Output into the MS-20 or as 
additional into the DE.

Thank you very much for detailed reply. It looks like a bit out of my hands...
