Order of Receive Objects

Edward Loveall — Thu, 10 Sep 2009 00:50:42 +0000

Hello all.

Quick observation/clarification/question.

[receive] objects seem to bypass the normal left-to-right/bottom-to-top message order. Instead, it seems that it’s based on creation order. Specifically, the one that was created most recently receives first. Here’s an example:

– Pasted Max Patch, click to expand. –

In this example, if you hit the top bang, the print out should read 1 2 3 4 because:

I made the [r test] connected to [print 4] first, then the [r test] connected to [print 3] etc down to 1.

Note:It seems that when you copy/past the condensed patcher, it doesn’t retain the object creation order. I got 3 4 2 1 when I pasted this back in. You may have to recreate the experiment your self.

Is this order documented anywhere? I can’t seem to get my finger on it. Any other thoughts in making patched with send/receive objects more robust?

Using send and receive is typically a scheme where you hand over the order to the gods. That might explain why it is not documented. If I remember correctly, in max4 it would be possible to change the order by sending an object to the back or bring it to the front. Anyhow I intuitively abandoned the idea to simultaneously use sends and receives and to care about order.

Actually, it is documented:

Quote:
The order of reception by two or more receive objects is not deterministic.

You’d have to use unique names if you need order.

Thanks johan

Most helpful. Bummer that there’s no order, but it’s good to know for sure!
