Hey Edd..... what do you consider a sequencer????? Are you looking for onboard auto-accompaniment or just the ability to program stuff in???? Like arnothijssen said, there are some other options out there.... he named the Roland G-1000 which is probably very similar to the PSR-740... sorry, I haven't used either of them...... I don't know about the bios issue either, all I know is what I read online and what I can gather from the specs on these synths (I do a LOT of research on here) The G-1000 has programmed "styles" which would give you good accompaniment, I think it has a sequencer too..... as for the modulation, pitch bend, etc..... Almost every keyboard in that price range will have that, the G-1000 is no exception, and it has 64-note polyphony (though I don't know how well it handles the polyphony) The Roland XP-60 is also worth looking at.... the only thing that would be lacking that these other two have is accompaniment styles... The XP has good sounds, 64 polyphony, modulation/pitch bend joystick, floppy drive, etc.... it's price on www.zzounds.com is around $1300

It would probably be easier and better for you though to go with the PSR-740... seeing as you already know how to use a PSR keyboard. The PSR-630 you mentioned having is probably an earlier model than the 740. The 740 is Yamaha's best workstation out there right now (leaving out the multi-thousand dollar PSR 8000's and 9000's of course) Plus you have onboard speakers with the PSR... (neither of the Rolands have onboard speakers) I would guess that since the *40 line of PSR's is a completely new line, that Yamaha would have fixed the problems they had with the earlier *30's I say go ahead and get the PSR-740.... it's the best thing out there for what you want (at least that I can find) Like sk880 said.... if you want, you could probably do better by spending more (around $500-700), but that's almost half again as much and the 740 will probably do you just as good. Hope I helped you.
