Step sequencer (Step by step) script for Arranger view

[Frac-Capitaine]

Hi.

I am trying to create a step sequencer script for the Nektar Aura (can work for all kind of controller). I have already create a script that work fine in the Scene view : scene/track navigation, clip creating, step by step editing, etc. I try to expand the script for the Arrange view, but I saw nowhere in the Bitwig Control Surface documentation or here the way to create clip in there.

To create a clip in a Scene view I use this code :
"trackBank.getItemAt(0).getClipLauncherSlots().createEmptyClip(0,2);"
with "trackBank = trackBank = host.createTrackBank(1 , 0, 1);"
But how to access to the Arranger ?

I tryied to create an Arranger object : "tArranger = host.createArranger();" but then ?

Thanks in advance.
