Routing and Control for Multichannel .WAV Files : Creating a Multi-Miced Drums Library in Kontakt

To individually control their pan and volume you'll need the channels in separate groups... that's the standard method for multi-channel drum libs. You can keep your robins in sync using a scripted robin rather than the built in method.

There are many many different ways to do it. Here is just one possible way.

For drum libraries, I put my robins on different pitches, starting for example at MIDI note 0. Then the robin is which note you play.

So you allow the necessary groups (which contain the channels you need), and then play the correct note based on the current robin. This example assumes 10 robins.

on note
    disallow_group(ALL_GROUPS) // don't allow any groups
    if(EVENT_NOTE = BD_note)   // if the input note is the bass drum trigger note
        for index := 0 to num_elements(BD_groups)-1   // allow all groups needed for bass drum
            allow_group(BD_groups[index])
        end for    
        BD_robin := ( BD_robin + random(1, 9) )  mod 10 // find a new robin, random not the previous
        play_note(BD_robin, EVENT_VELOCITY, 0, -1)
    end if
end on
