Reply to Senior Project help

Hello everyone,
I'm working on a midi-controller for a senior project as an electrical engineer. I just need help completing a required survey and would really appreciate the help. So please answer the following questions:

• When and why do you use a midi-controller?
• Walk us through a typical session using the product.
• What do you like about existing midi-controllers?
• What do you dislike about existing midi-controllers?
• What issues do you consider when purchasing a midi-controller?
• What improvements would you make a midi-controller?

-Thank you
