Waldemar Pawlik Posted June 26 Share Posted June 26 (edited) I created a song in Band in a Box and rendered to individual track wav. files. Then imported the individual tracks into CbB as I have done on previous occasions with no problems I had made sure that the CbB tempo matched the BIAB tracks before importing, however on playback in CbB the key has changed to four semitones lower. I have done this many times before without fault. The stems from BIAB play in the correct key in Windows media player, as does the song I created. I haven't changed any settings in CbB, so this is strange. I really don't know where to look for a solution, so turning to you guys.

Bristol_Jonesey Posted June 26 Share Posted June 26 Could be a sample rate mismatch, but four semitones is a bit drastic Link to comment Share on other sites More sharing options...
Waldemar Pawlik Posted June 26 Author Share Posted June 26 I have matched sample bit depth in both programs but it does not help. I have now imported the stems into Next defaut install, and the stems play correctly. Go figure??????? Link to comment Share on other sites More sharing options...
John Vere Posted June 26 Share Posted June 26 Do you drag and drop the wave files? That's how I do this and never have a problem, I'll export stems from Band in a Box if the track can't be midi. Like the Steel Guitar. The pitch issue you describe is most always caused by sample rate miss match. I have my entire system top to bottom using 48. I set it in Windows sound settings, My Audio interface control panel, then all Music Apps and Video software have an Audio setting which I choose 48. Sonar/CW will convert any audio to the projects sample rate when you drag and drop the audio onto the track pane. You'll see a busy bar in the transport telling you it's converting the audio if it was a different sample rate. Link to comment Share on other sites More sharing options...

Approx. four semitones (approx. minor 3rd) sounds about right to me. Example: C to A : 220 Hz to 256 Hz = a ratio of approx. 0.86 [ 220 / 256 ] the 44.1KHz to 48 KHz ratio = approx. 0.91 [ 44.1 / 48 ] Comparison withdrawn; see discussion below. Edited June 26 by User 905133 edit; changed the example back, since there are different frequencies for C according to different sources 1 Link to comment Share on other sites More sharing options...

David Baay Posted June 26 Share Posted June 26 48/44.1 (a factor of ~1.09 ) is in between a semitone (~1.06) and a whole tone (~1.12). No idea how you would get a 4-semitone error. Link to comment Share on other sites More sharing options...

No idea how you would get a 4-semitone error. I stand corrected: a 4-semitone musical difference based on a 48Khz v. 44.1Khz sampling error / transposition would be drastic.

Waldemar Pawlik Posted June 27 Author Share Posted June 27 For thos familiar with BIAB, the culprit was in the Key selection box. The song I was creating is in the key of E, which is what I typed into the chord sheet. I then thought to be tidy and change the key in the selection box from it's default C, to my key E. I think the reasoning behind this box is to show correct key #'s and b's when printing a lead sheet. However, it also changes the pitch of what CbB sees when it imports the stems. No idea how? I changed the key indicated in the box back to default C, and everything corrected itself. Trap for the unwary. Solved 1 Link to comment Share on other sites More sharing options...
Glenn Stanton Posted June 27 Share Posted June 27 (edited) in BIAB - there are two distinct options for setting the key: one sets the key and changes the chords etc, and the other simple sets the key and leaves everything else intact. in the latter, it may influence some of a regenerated performance, in the former, it will definitely change things ? basically been this way forever (measured in BIAB years)...
