Here's a chat with PG Music about a problem I'm having. Perhaps one of you can recognize this problem and tell me whether it's fixable.

you: I have BIAB V10. It works perfectly on the old Win98 computer that is connected to my piano.
you: I have just installed the BIAB 2007 demo.
you: When I record a song on that system, the piano does not sound right.
you: That is, it does not sound right while I am playing.
you: The sound changes over time, and may be related to the fact that the bass is being played through the piano (i.e. MIDI out from the computer).
you: This is a showstopper for me (that is I won't upgrade unless I can fix this).
you: Did I describe it adequately for you to recognize this problem?
you: Thanks,
Kent: Not sure exactly what you mean here... is all the sound is coming out of your piano?
you: Yes, that's right.
you: It sounds fine until I start the record operation with BIAB.
Kent: what kind of piano is this?
you: Yamaha P90
Kent: Does this thing have any other sounds, or is it just piano?
you: It has other sounds.
you: I use the piano for the bass sounds from BIAB.
you: I have the drums go through the sound card.
you: I use the midi mapper to handle that
Kent: really? is that part already set up?
you: Yes.
Kent: So when you're playing a song, are the correct sounds coming out of the keyboard?
you: Not really. The notes are correct, and it sounds like a piano, but the tone quality varies substantially from note to note.
Kent: that would probably be a velocity issue, i'm thinking
you: It works fine with BIAB V10
Kent: it's possible that in version 10, all the notes had the same velocity... what happens when you record?
you: I get those results while doing the record. When I play it back, the notes sound fine.
Kent: do you find that this is affected by how hard you're hitting the keys?
you: No. I can sit there and play one note over and over, and
you: the sound changes. The effect is like one of those rotating speakers, but the change is not regular
you: Kent, I think I will phone your tech support line so that I can demonstrate the problem and interact more quickly.
you: Thanks for your help.
