Line-level is line-level. A keyboard will be putting out an unbalanced
line-level signal, and a DI box converts that to a balanced mic-level
signal (usually XLR) for a soundboard. Since most computers don't have
XLR (or other balanced) input, a DI box is not needed or useful.
Some computers/sound cards only have unbalanced mic-level inputs instead
of line-level (and some can be configured for mic or line); if you don't
have a line-level input, your best bet is to get something that does
(even a basic USB sound "card"), not to amp up the line-level signal to
mic-level (especially because most of the mic inputs are mono, not
stereo).
