I think I may well be being really slow here.

I want to create this logic:

if either or both of two values is a one, output a 1, if not output a zero (only 1s and 0s will be used)

I also want both inlets to be hot, ideally without a trigger bang float.

I hope that makes some sense. Thank you very much for any help

I'd use an [||], which is another way to say 'or', and that dreaded [t b f]. I mean, that's a standard way to make secondary inlets hot in pd. You can hide it up in an abstraction, [pd or], if you need it to be a single object.

Maybe this works:

/ num a]
|
| /num b]
| |
| [t b f]
| / /
| / /
[ + ]
|
[> 0]
!
/num result]

limiting num a and num b to 0 or 1 only.
Best regards,

Sumidero

Thanks for these responses. Sorry for not replying sooner - I have been away. If these work I will try to post the solution

Thanks.It's useful.
