I had some time to try out a few things today. I finally got the Tascam US-1800 to work with a very old version of Cakewalk. Everything works, playback thru headphones, thru monitor speakers and no bleeding of tracks. Part of the problem was with the USB power cord but also in selecting Tascam US-1800 in the playback and recording section of Audio Devices of the control panel of the computer. One problem I am having is not being able to get a stereo signal in each track. When I use the pull down below each track with has left, right andstereo picks, the stereo play left and the left plays stereo so it doesn't record in stereo which won't really do fhat we want. Maybe its a bad power cord or USB port, I'll try that soon. The computer I'm using is a Dell with 2GB of Ram and a 256 MB hard drive. I use a tube pre-amp on the vocals and a headphone amp for playback. Now everything works off of the Tascam, all the controls in one spot, its awesome. Thanx.
