Arpegiattor Catanya - How To Connect It To Renoise?

I have
Energy XT

and newly bought Catanya

How to setup these plugins???

What do you want to do with them? i.e. have one instance Catanya controlling one track (easier), or I guess as you want to use Jthalamus, multi tracks (less stable)

This explains how I tried to use Jthalamus a while ago, may be useful to you:

Otherwise I would just load energyXT VSTi in renoise, add Catanya in that and any other VSTi that you want effect with its MIDI. I do not have Catanya to test this Im afraid.
