Andrew Hugill was my professor at university. This resource has been around for years but recently, he made major updates to the website. All the recordings were made in the studio in my university. Unfortuantely, the video quality is not great for today.
Oh yes. This has indeed been around for a long time in a different form. I was in discussions with Andrew Hugill many years ago regarding improvements and some corrections and he was very good at getting back to me quickly. Glad to see he has updated the website and all the info is still accessible.
