USB Midi Doe Not Work in AUM with Yamaha KX61
I'm not sure why. AUM does not want to start when my Yamaha KX61 is connected to AUM. I can use my keyboard, but with the midi 5 pins.
The cool thing about USB midi is that it also deliver power to the keyboard.
At first, I thought it was something related to the clock of the Yamaha but nop. I browser the option on the Yamaha to select "USB MIDI".
But only MIDI 5pins works. I don't know if it's a specific issues or a general issues, something that I'm missing.
Oh and, when my Yamaha KX61 is connected via USB on my iPad, 0 music starts, it's not just AUM.
Any idea why?
