V-Trigger to S-Trigger Conversion

A Moog speciality

The earlier Moog synths uses a trigger system that is different from the mainstream. Today almost all synths use the standard +5V gate impulse for this purpose. But the Moogs use the S-Trigger instead, where the voltage drops to zero.



Devices capable of sending triggers, may have a built-in setting that changes between the 2 formats.

Converting triggers and gates from e.g. Eurorack and Roland gear can be done with a simple cable with a few components.

This can be purchased from established modular synth outlets, like Schneiders Laden in Berlin.

If you are handy with a soldering iron  you can also make one yourself quite easily.
