Merge CHOP with Two Audio Files

Dear all,

I was looking into Merge CHOP to merge two audio channels into one. When I linked the files to Merge and try to Audio Device Out, the result of the output only contained one of the audio channels. By switching the order of the Input OP in Merge I can hear the other audio file. But what I want is to combine both, but it is not working.

Does anyone know why it is like this? Or is the Merge CHOP only to collect channels but not actually merge the content inside? Maybe I misunderstand this operator?

Thank you.

This. You want to use a Math CHOP, adding both channels together to create your mix.

Ah! Yes, now it is two channels combined!
Thank you!
