A tutorial on how to use the Mixer?

Unless I'm mistaken, a while back somebody wrote their own tutorial on how to use the Hauptwerk Mixer. However I've been unable to locate this - if it exists - within the Forum. Can anyone shed light on this matter?

My HW 5 tutorial is still online at https://iainstinson.com/hauptwerk/

Other material is available …. For example https://forum.hauptwerk.com/viewtopic.php?f=17&t=19438&p=148246&hilit=Multi+channel#p148246I

Many thanks, Iain. This is the tutorial document I was thinking of. Thanks for the link - this will be very helpful.
