Well, here's the ASCII version of the circuit that appeared in the March 1982 Keyboard (Kraftwerk on the cover!) Note that this is for a 0/9v v-trigger. If you need 15 volts, I'm sure it's a simple change. This will produce a voltage trigger in response to an s-trigger out. The trigger Off voltage will be 0 or 9 volts. ___o ___________ Close the switch to use, open / | 9-volt | it to save the battery life. |-----o o---- +| battery |-- ground ________________| On |___________| \ \ / / 10k \ 10k \ / / | |----------------------- to tip of jack | | sleeve to ground | 100k / ___________|___/\/\/\___|/ | |\ 2N3904 or equivalent 1 -|- S-trigger \ _____ in | 2 | | | --- | ground - --- ground -
