I recently upgraded my 2017 iPad Pro to this years model. The lack of headphone out was never going to be an issue, until today. I want to hook my Midi (USB) keyboard up as a controller for Cubasis or GB. Easy enough, i just a normal USB cable. Problem is, i now have to use the built in speakers of the ipad to monitor. Not ideal. Ive got two USB C multi Hubs that get around this, with one big issue. Neither allows me to control the volume of the ipad playback. Its set at 100% and very loud. I could use a small mixer but it’s starting to get complicated and a lot more wires than I think it should be. Does anyone know of a hub that will allow volume adjustment on the ipad? Or any other cheap way of doing this?
