Kent solved it:


Kent: Ok, I have an idea we can try...
Kent: let's go to Options, Preferences please
you: OK, just a sec
you: OK, I'm there
Kent: cool, is the box marked MIDI Thru checked right now?
Kent: try unchecking it, and make sure Local ON is checked
you: I'm not seeing that box
Kent: oops, sorry... my fault
Kent: click the MIDI options button first
you: OK, I've done that and...
you: It looks like that fixed it!
Kent: oh good... that's the first time I've encountered that problem, glad we figured it out
you: Yes, looking good.
Kent: cool, anything else?
you: Yes, here's the next question:
Kent: ok
you: I use the midi mapper so that I can send the drum sounds to the sound card
you: and send the bass and piano to the keyboard
you: However, XP apparently doesn't have a midi mapper.
you: In the future I'd like to connect my piano to my XP instead.
you: Is there any way I can send the different instruments to different places?
Kent: Actually, I didn't even know it was possible until you said that you had done it.
Kent: I'm pretty sure all your MIDI has to go through the same device
you: OK, that's too bad, since the keyboard doesn't have drum sounds
you: Back on the first problem: Can you explain in a few words why unchecking MIDI thru fixed the problem?
Kent: basically, when MIDI thru is on, the MIDI signal passes through the computer, and back out through your piano... Local ON was also turned on though, so every time you hit a key, that would trigger a note directly through the keyboard, and the computer would trigger the same note at the same tim
you: OK, thanks.
you: Thanks for your help. That does it for me.
Kent: so now, when you hit a key, it triggers the note directly, but the computer isn't giving it a note instruction at the same time
Kent: coll, have a great day then
Kent: *cool
