I purchased the course for the Tascam DP-006. I learned more in one video, than I did trying to read the manual. It is a wonderful machine, and just by watching the videos, I am getting the most out of my investment. I just don't understand why they don't make manuals user-friendly. However, the videos are great, and explain what is needed in full detail. In addition, ProAudioXP will answer any question that you have, usually within one day. I am very impressed by the videos, the company, and the support! I highly recommend any courses offered, as you WILL learn what you need to!
