Question for SX-R4+ Users: My dilemma : I have a R4+ and SX-ES84 Mixer

[valpri31]

My question towards the members using the R4+ RECORDER.

I have cast  of 12 scripted parts. Obviously more than my mixer, ( Digital out option on my mixer ES84 to R4+) , if  I go to physical inputs XLR 1-4 and 2 more lines on TA 3 F 5 and 6.  I am now recording 8 digital in ( 1 Mix-Mono; rest 2-8 ISO) the added channels going to Tracks 9-16 are part of the same poly file but not in the Mix. More to it 9-14 are analog  post fader- not ISO pre- fader ?!

So, how do I craete a poly file with normal Mix- ch1, and the rest normal 2-14 iso ?

Let alone feeding the Public IFB Lectors for Company .

Many Thnks to all members in regards to my dilemma .
