Would Tangerine Dream fit into this as they are an electronic group. They provided the US score for Legend. (There is also the original European score by Jerry Goldsmith)
Interesting question, as they were using a lot of analogue synths at the time. Some of the sounds were Yamaha digital FM (ala DX7 type synths).
The problem with this thread is that the poster is looking for scores done with "Sampled" orchestral instruments, period. However, "digital" would be anything scored with a modern synth (Access Virus), sampler, or computer instrument.
I am a long time fan of digital and analogue synth music, whether it be a John Carpenter (HALLOWEEN) or Tangerine Dream (LEGEND) score. Many of those scores include sampled orchestral instruments, like the TERMINATOR orch blasts, NIGHTMARE ON ELM STREET 3 strings (done with a NED synclavier) or the instruments used in a movie called THE FINAL APPROACH (also synclavier). See also, 2010 (SPACE ODYSSEY sequel) score.
There are many all digital scores, but a lot of them combine either samples and electronic, or samples and live players (solo instruments on certain tracks, which add realism).
Check out this 1991 movie scene, from FINAL APPROACH. Watch from 3:30 to about 8 minutes, which features a cool score and sound FX. I believe most (or all) of the music and FX were done on the synclavier sampling system.

Of course, a lot of indies use East/West and Vienna Symphony style sample libraries. Check out the TERRITORY 8 trailer music.
