I’ve had an old M-Audio Uno midi interface for ages and it’s always worked great. Last week, a light bulb went on in my head that I could get another and use them together to get usb hosts (computer, ipad, norns) to talk midi to each other. It is extra wiring (there are a few specific solutions out there for this) but it works! Had a lot of fun with this tonight and am pretty excited that these things are now able to pass signals back and forth.
