hi there ...

im writing a bunch of patches to control my analog modular synth system via control voltages. so far im creating synched euklidian patterns. here is an example of what that sounds like with my modular:

now i want to combine two pattern into one and have the following problem. the patterns generate synched bangs and i want to output where they overlap that is where two bang arrive AT THE SAME TIME. ive found a patch here that does something similar with [spigot] but regardless of the timing.

i can use two spigots in a row that open and close but how do i make shure that happens at the same time?

use the [trigger] object. basically, it assures the the right most outlet sends its signal first...so, everything that you cascade on from that will also be sent before the leftmost outlet is sent.

thanks! i tried that but i need two trigger objects one for each channel and they have to send a signal at the same time and not after each other which is something i dont know how to do. the two bangs arrive exactly at the same time and they have no "length". i hope im making sense

When working with finite computers there's no such a thing as "at the same time". One piece of data will always be scheduled by the CPU (or the pd runtime) to be sent before another, even when they appear to be ariving simultaneously. Order of execution should be enforced like mod said by using [trigger] objects, there's really no other way, unless pd one day runs on something like a quantum computer Maybe you could upload the patch (or a part of it) to demonstrate what you're actually trying to achieve.

what im trying to say is everything in pure data is in sequence but how do you detect in synch? i could open a gate and close it after 5 mseconds again and anything thats within that frame is "at the same time" but thats cheating.

ive done the 5 ms gate solution this is a modified patch i found here. it works but im not shure if this is the most elegant solution ... and it will not work for bangs that are closer than 5 ms which is no issue.

@domien ... thanks for the clarification. im just listening to your music on soundcloud, thats some outrageous stuff, brilliant!

perhaps slightly more elegant would be with [timer], but there is probably a place at which you separate the control stream into the 2 metros? at that point I would instead use 1 metro at the higher subdivision, and every time they would sync up have a conditional (a counter with select) to do whatever you want

[timer]! thats what i was looking for ... the metros are just there to test the logic. the bangs come from totally independent abstractions that are synched to one ticking clock. great forum, thanks!
