Sooo,

You want an output that looks like this:

And the the seven millisecond timing is important to ... what level? Since you can time with either milliseconds or microseconds, a precision of a hundred ppm or so seems like a reasonable limit.

That is right Chris, that is the target.

7 ms...you know, I just sad something. 10 ms is also OK.
Modern Buchlas using 4 ms triggers, in Eurorack modular the average is (I would say) 2-10 ms.
Basically, 7 was just a number, not critical, but it should be constant.
