Just a question.
When say dark ambient you reffer to bands like Lustmord, Inade, Kammarheit, Land Fire, Northaunt, Schloss Tegal, Trepaneringsritualen and many other one?
X1L3 Shard is a great module.
Schlappi engineering and Noise Engineering modules too.
Plus a good filter and a huge reverb everthing is said.
