I have Sibelius G7--goal is to be able to play a MIDI guitar into computer and produce a TAB or Notation score for students--licks and solos, that kind of thing. I have a MIDI pickup on a strat, and I have a Godin classical, and I have a Roland GR-1, which I'd just like to use as an interface (local off?) but the problem is, the latency makes it impossible to play live. I called Sibelius and they set my GR-1 as my synth (local on) but the MIDI map is all off (not General MIDI) so the click track doesn't sound like percussion. It tracks kinda-sorta OK, but I don't think it's my answer. I've been told the problem could be w/the GR-1, or my sound card (Sigma Tel Audio integrated). A guy at a music store suggested the AX-50, but it's pricey. He said it tracks better than the Roland GI-20. Will the AX-50 solve my problems? Will it take over for the sound card, or will the card's problems (if there is one) still be apparent. I don't care about sounds at all, I just want to create scores LIVE, and not tediously inputting stuff via mouse or cpu keyboard. And I'd like to fix the problem w/o spending money on three or four different things before it's fixed, and since I'm not doing anything major, it seems silly to buy high-end stuff. What's the fix?
