I have been struggling with this project for some time. I have quadraphonic media in vinyl and tape format that I want to save in digital form before they all turn to dust. Seems simplistic in my mind, but I am frustrated by the mechanics. I have the equipment to decode quad records and two quad capable tape decks. I know how to use that equipment. I am stymied on recording this media so that I can save and replay it via computer or DVD. I keep running into issues where the hardware insists on recording in, or mixing down to stereo while saving tracks. I have tried various daws with their seemingly steep learning curves with no joy. I just want to record the four tracks, save the four tracks and playback the four tracks in digital format. I have a PC running Windows10 64 bit and a Mac. I have a Uphoria UMC 404HD and a OPPO 103, (have not utilized the OPPO). No combination of these have so far worked for me. Is there a simple or down and dirty way of doing this? I think at this point I would pay to have someone show me how to do this successfully as I think I'm too stupid to figure it out. Any help appreciated.
