Received my iCA4+ last week and been trying to get midi setup working with Reaper.
This is my setup: win7 64bit pro with Intel Core i7-5820K @ 3.30GHz Hexacore with Akai MPK49 midi keyboard.
After installing drivers and iConfig, everything worked fine. Akai showing up in midi routing etc...
But since I hooked up the iPad, I can't get midi to work, and I got some error messages while trying out different routing setups... IConfig shuts down... The Akai still shows up in iConfig. I reset the iConfig settings in iPad app and I tested the Akai, it works fine when I hook it up straight to pc, so this is my workaround for the moment: Akai in pc usb, and doing the routing inside Reaper, not using iConfig.
Any solutions or tips? Thanks!
