Machinedrum internsampling as the Octatrack master8 track?

Hello there !
I’m trying to use a track on machinedrum to control all the others with filters, soi i’m using a Ram R1 to listen and add fx on all tracks.
The fact is now that it keep listen the dry tracks signal when I sample, can you tell me settings to sampleand mute dry signal,
I have problem when it comes to deal with the “cue” and level settings,

And is it an other way to use input machines or something without jacks to apply fx on a master machinedrum track ?

The track I want like a master has to be the only one going to the stereo output. How can I route this like an Octatrack master channel ?

Thanks as always guys !!
