Hi, was just wondering if there is a function allowing If/Or routing in Pure Data. What I need is an object that will output 1 if the input data is between either of two different ranges (say 0-50 or 100-150) and if it isn't output 0.

I've looked at both the relational operators and the Expr object but can't quite get my head around how this particular situation would be handled.

Thanks in advance,

Jon

You're on the right track with the relational operators. You can use the [>=] and [<=] objects to set your thresholds. These output '1' when the criteria is met.

You then want to know when the input is within the lower and higher thresholds. [&&] will output '1' when both inlets receive a '1'. So connect the outputs of your range thresholds to [&&].

Then you want to know if the input is within one of the two ranges you have (0-50) or (100-150). [||] will output '1' if either inlet receives a '1'. So hook up the two [&&] outlets you have to [||] and voila!

Execution order is very important here so use [t f f] to make sure inputs are received at the right time. The operators will need the right inlet before the left.

This is also possible with the [moses] object but I'll leave you to figure that out

Thanks very much, the [||] object sorted out all my problems!
