I am starting simple, but for some reason I cannot find any examples online and I stuck with my task.
I have a usb midi keyboard, Arduino Yun, and a synthesiser that can accept midi via usb. The problem is that the synth doesn't send a voltage through its usb and the keyboard has only one usb that is used to send midi data and it's powered via it at the same time.
My idea is to use my Yun's USB host (which sends voltage too) to power my midi keyboard and grab all incoming midi data from the keyboard, then simply pass it unchanged through to my synth.
Where do I start? Do I need some python code for it or everything can be done with sketch code? I've done few arduino projects but I am new to usb host functionality . This is my first step, later I would like to also convert usb-midi to 5-din-midi (old school connection), but that's different story.
Can you guys help me and point into the right direction? Anyone done something similar on Yun? I've seen some examples done on different boards, but it's all overcomplicated, I need simple read/pass usb solution. Thanks!
