i am trying to find a computationally fast way of outing a 1 if 9 separate streams of data go over a threshold. Kind of like the below patch, but working... any ideas? thanks in advance, rgb

if-9-streams-are-greater-than-x-problem

This assumes independent streams, if use change the [pak] into a [pack] it will only trigger on the leftmost input

your direction is possible as well, but you had some problem with the syntax and proper conditions, see a 3 input for dependent and independent streams here

I don't know which solution will be the more efficient, but this also depends on whether the streams are independent or not

You can save some patchchord rsi and several comparison objects by using a couple of zl objects to process each element of the list (this will work for lists of 'any' length by just adding extra inputs to the pack/pak object):

Whether its more cpu efficient than a single [if] I don't know.

The patch can be easily modified to allow you to specify individual thresholds for each list element (via coll lookup):

if 9 streams are greater than x problem....
