I have a bunch of music that I recorded onto audio cassette tapes using my 4-track Tascam Portastudio 424MK II a long time ago. Now I would like to transfer those tracks to digital tracks on my PC using my Cakewalk home studio 2002 software. I would like to store each track separately on my PC. The only problem is, with my current setup I believe I can only transfer 1 track at a time. I would like to transfer all 4 tracks at once, but I don't have enough inputs on my PC to have a line in for each track.

Would anybody have an idea of what I need to buy in order to have a direct line from each track to my PC? Or is there a way to do this by sending all 4 tracks to 1 input (using my current setup)?

Thanks :)
