AR/4/K Din-Sync Voltage Info

Probably not much use (or interest) to anyone
But this came up in a recent discussion with @void
It relates to a long term idea I have to create a clock divider to work on the Sync Pulses … coincidentally Daren Ager subsequently made a Din Sync box doing just this … but i’m into finding my own solution, potentially using the Run High Voltage to power the dividing circuit
.
stage one was to see how Elektron utilised the Din Sync ‘standard’ and whether all pins were used, and in which way.
.
Anyway, for posterity, a sketch …

fwiw - i’m keen to hear if the power on state (i.e. clock active) seems like a good idea for vintage gear, almost like a pre-count ?
.
it seems odd that it should be running from the get go when a double stop (song position pointer 0) is just the same as when you turn on ? !
.
the voltages are nominal, plus the pulse clock is too fast to be of any other use, so this temporary breakout cable was just a way to try things out before wiring in some circuit (& maybe power) - it may depend on how fast i can make the electronics ‘play’ when the Run signal is high - i guess it will, but an arduino based venture may falter initially, anyone have any insights on that route ?
