I have just got started with Garage Band and find it easy to use. But I have run into some small problems that I cant figure out. When I turn monitoring on while recording a real instrument, it plays for about 6 measures and the pops off. In order to get the monitoring back on for that track I have to close the program and open it again. This frustrating, since I would like to record in real time with real instruments and am not able to. I am hooked to a usb port with a TELEX device which is a real cheap way to input real instruments into usb. Any help would be apprecitated.
