I use my Thinkpad 380Z (and my desktop) to drive my 740 using XGworks. This gives me access to the whole synth inside the 740 with essentially the same sort of capability as an MU80 or MU100 but with more DSPs and different non-XG instruments. In other words, I can change the sounds on the 740 much more than I could just using the keyboard features. Because of this, I now use the 740 as my exclusive MIDI synth since the sounds are far better than any but the high end sound cards (such as the SW1000XG). One of the nice things about XGworks is that it can generate styles just using the melody and chords straight off a fake sheet so you don't need Band-in-a-Box or Jammer and you don't have to swap programs because you have a powerful sequencer at the same time. The only problem with XGworks is that it doesn't really cater for keyboards but I've fixed that problem for the 740 and 2000 by reconstructing all the definitions and tables.
