[RWP] Only track 1 it recorded

[Alexis ROBIN]

Dear Reaper specialists,

I met a very simple problem, that I can't solve, beginner who I am...
I need to record two tracks, guitare and voice. On the reaper 
preferences / Audio Device Settings, I selected my Roland Quad Capture 
and in input I set on Input 1 and Input 2. Input 1 guitare, input 2 
microphone.
When creating a project and insering two track, then arming and 
recording, only Input 1 it recorded.
To record input 2, I have to set the two input on input 2. Else, this is 
the input 1 whose recorded.
I don't know if I'm enough clear.

But if you have an idea and understand my bad english, thanks you in 
advance,

Alexis
