How to Edit in 7.1

[Zakk Rokkanno]

Hi

I need to edit in 7.1 8 channel sound for both music mixing and also video audio tracks

For monitoring I have a strix 7.1 headset with 8 discrete genuine channels [not simulated]

In Cakewalk I see in advanced I can select several 7.1 profiles [film / music etc] but  when routing I can only select strix channels 1/2.

 

I want to be able to output to the other channels also 3/4    5/6  &  7/8  so I can monitor my mixing in true 7.1.

Why are the channel mapping options for those not available to select and assign to my tracks ?

 

I am hopeful there is a simple solution for this as it must be possible to monitor in 7.1.

Thanks in advance for any advice I can be given.

I am new to 7.1 editing so the step by step treatment for 'dummies' would be ideal

 

cheers
