I have purchased a teensy board 3.5. A tech friend gave me his diagram of how to connect an organ pedal board to it. That stage has been successful and had the teensy board been recognized by windows settings as a usb midi.
I have followed the instructions on the web site (https://www.pjrc.com/teensy/td_midi.html).

Now i have no idea on what coding is needed and would love some help. I have 3 usb midi keyboard controllers that have also been plugged in and no problems with those.

I feel i am missing some coding into the arduino program. I have pressed the tick buttom and pressed the button on the board. For the first coupe of attempts the phase "hello world" kept repeating over and over. I have uninstalled the arduino program 3 times, on the 4th windows has accepted it as a usb midi. So please what am i missed??? you can respond to my email address hondacruiser2001@yahoo.com
thanks in advance
