I use Logic Pro X on a Mac Mini in my home studio. Using this system with Pod HD 500 and Axe FX is simple. Both have a USB out that plugs right into the Mac Mini. But unfortunately Kemper doesnt have a USB port. It has electrical SPDIF O/P. In my Google research folks have needed to invest in converters that have not solved and have created other problems(sync issues, etc). After spending $2000+ Im not interested in investing in more gear that may or may not work. I find the lack of USB port very annoying. If anyone has a tried and true solution to this dilemma, I love to hear it.
