so, i know very little about this other than spending a shitload of money on equipment that i cant get to work properly. my current setup is a microkorg synth running (jack cables) into a behringer xenyx mixer ( i have it running into LINE 1 , but i dont know if this is correct). i have the cinch cables running output on the mixer (cd tape slot) into a behringer U -control box which is USB running into a macbook. i am fucking around with garage band just to start out but the program isnt recognizing any of the equipment. does anyone know why that would be, or any particular settings i need to change on the mac? i have the sound prefernce in my systems preference set up to USB audio in and i am getting NO response when i add a new track to garageband using software insrument (which is stated as the desktop keyboard OR other midi, usb, firewire device) . did i possibly buy the wrong mixer. is it not MIDI compatible? also, i was under the impression that it is a interface regardless and would work.i am losing my mind. ANY input is appreciated.
