Trying to wirelessly have registrations on sd90 come up when I use for score application on my iPad. Using Yamaha MD-BT01. I finally got them to pair, I watched a video where the guy used an USB connection instead of wirelessly and showed the midi set up to use, but does not work for wireless. When this works the registration on the Ketron comes up when you sroll to a music score on the iPad. Can anyone help on the midi set up on the SD90 to make this work?
