This is a wonderful training DVD for the Roland Juno-G synth. It is very thorough and laid out in a logical way from beginning to end. The trainer, David Wills, is an amazing instructor. He is extremely knowledgeable with music technology, and clearly explains almost all the aspects of the Juno-G synth. David brings to life many of the things that one needs to know to perform both basic and advanced operations on the synth.The DVD starts with an orientation to the front and back panels of the synth. It then moves on to using the controls appropriate for playing. Next David covers the many onboard effects, building a song with drums and other parts, editing, and then recording audio. He also covers connecting the Juno-G to your computer, as well as advanced functions such as editing patches and rhythms.During his presentation, the video switches to a close-up view of the part of the front panel that David is working with. This makes it very easy to follow what he is doing. Finally, the DVD has navigation menus that allow you to jump to different sections, which is handy.I am very satisfied with my purchase.
