Hi @Tom David Frey! Sorry for not responding sooner.
We have an article that explains the ins and outs of ImpulZ here: https://vision-color.com/products/impulz/learn-how-to-use-impulz/
And here's a video tutorial that shows the basics in Resolve. Skip to the 18:20 mark for the Cineon Workflow.
We also finished ImpulZ 2.0 which will introduce full ACES and HDR support and we're currently preparing the launch. ImpulZ 2.0 is a complete overhaul of the library that will introduce a number of new and exciting workflows. Stay tuned!
