My problem is as follows: I play a life music and record it. Then, through the mastering menu ı choose classical rock. start the mastering. The program runs the mastering and completes it, however it shuts down the magics screen completely before ı can control it and when ı restart magics, ı cannot select roland edirol ua-4fx. the external sound card cannot be selected in asio recording mode. so ı have to shut down my pc to run it again. ı have tried several times to launch it but it does not work, ı cannot select the ua 4 fx section in asio mode. ı would be pleased if you could assist me how to proceed. do ı have to install the program (over the magics internet page) again? Or can you tell me the reason for such an error message. thank you in advance for your kind assistance.
