The Tascams are for people that don't want to use a DAW, for many reasons. Like me. Making a DP-32SD controllable over usb means making DAW software means managing and maintaining upgrades blah blah blah blah.
Remember our TEAC/TASCAM 4 and 8 tracks? This idea is them today. Just as not perfect as they were, but if you have that workflow already, they are pretty much the same except for what comes out of the tape machine, which is an SD card. It doesn't need all the DAW nonsense, there is way too much of that stuff out there as it is.
