Hi again! First, thank you for your answers, they have been very useful. But I'm gonna bother you again with a newbie question.
How do you gate flow, both control / audio?
I think max has a gate or so object. Writing a patch which treats a number of cases in different ways I was in a bad need of a gate-like object with for example an output selector inlet and an input inlet gated to one of N outlets according to the current value of the output selector.
I solved this by [pack]ing the incoming message with the output selector in front and then [route]ing it (and in case the selector was a symbol stripping the list selector added by [pack] before routing).
Regarding audio streams I find gating them by means of [~* 1] / [~* 0] multipliers too awkward, as a few N gated streams would clutter your patch with ~ N^2+3*N control connections needed to send 0 or 1 factor for each multiplier and them sum the outputs. But here I could use [switch~] (or derek's [switcheroo]) and subpatches with the plus of performance gain.
I could write some gate-like subpatches but first I would like to know if there is an usual way of doing the above which I'm missing, or some adequate external, specially for the control part.
Thank you again. Regards, Carlos
