Scott,
I would like to add my kudos for a great tutorial. It is well conceived and presented.
The only criticism I would offer is that, in general, the volume of the sounds is somewhat low. I know that the sounds themselves are not the point of the tutorial, but the imbalance is a little distracting and there are times when it would help to more clearly hear what is happening when they are being tweaked.
This has not kept me from learning what you are teaching, but I thought you would want to know about it.
Thanks for the course!
Jeff
