I'm considering one of the new specializations that includes the Pro Tool Basics course. Has anyone taken that course? I know you can download the Pro Tools First for free. However I do not have an MIDI controller, or an audio interface. I'm looking at the "what you need for this course" and to me it isn't really clear if you really have to have all that. How much would I really need to have to complete the course. Thanks in advance for your help.
