Behringer audio interface on mac does not show ins and outs in rew

[garethsnaim]

I am trying to work rew on mac as I am having crackling issues and all sorts on PC.

In the midi interface of mac it shows input 1 and 2 and output 1 and 2

However in rew it only shows as Behringer input 192k and output 192k and is not split by the separate channels.

How do I fix this please?

Could you attach a screenshot of your REW soundcard preferences? 1 and 2 would typically correspond to left and right (L, R) in the REW channel selector.

Here is on PC

on pc in the drop down boxes I can pipck input and outputs 1 and 2 but also I can add an secdondary output, which I cannot appear to do on mac?

On the PC you are using ASIO, which treats devices as a collection of individual mono channels. On the Mac, or on PC when using Java drivers, inputs and outputs can be multichannel with a channel selector. L and R in the channel selector correspond to 1 and 2 in ASIO. There's also a L+R option to drive both.
