What's causing this unexplained pitch shift?

I have two parts in a flute track (software instrument) and both had been working fine. However, last night while adding more tracks, I noticed that the second part now has an unexplained pitch shift. There's no automation whatsoever. Even when I copy the first part of the track to replace the second, the pitch shift does not go away. Any idea why this is happening?

Maybe you have, by accident, changed the track's transpose function in the inspector?

That may not be the case as I have the exact same region in an early part of the song and that plays perfectly. The weird thing is if I create a new track and place the region on it, it does the same thing. Even if I use the region that plays perfectly!

Anyway, thanks for your reply.

Hi,

1st Question: Did you use the global Chord track (=global transposition track)? That would explain a lot.

2nd: Did you try to copy this midi region between two projects? If not: Try out and report back.

3rd: Just to please me... look in the inspector if the original region has an entry under "transpose" Remember transpose in the inspector can be done at two different points: One is in the track inspector, and the second possibility is in the region inspector. They may be easily confused because they look so similar to each other. Look if you selected the correct inspector window by opening all inspectors (click on the little black triangles to the left). The one that i mean is the uppermost one.

1st: No

2nd: When I pasted the regions in a new project, it worked!

3rd: Neither the track nor the region inspector has any transposition data.

Here's another weird thing I just discovered. When I changed the instrument to piano, there was no problem. When I switched back to flute, the pitching was back too! Anyway, for now I've bounced the region sounding right to audio file.

Thanks for your prompt responses Foxboy.

Hi,

given everything else is un-transposed, there might be a slight chance the transpose is set in the software instrument. EXS24 has, for example, a transpose function. I also found that some of the instruments coming with it are in a false key requiring me to use the transpose function of the EXS anyway.

Good luck,

Fox

Another possibility might be that you accidentally put some pitch-bend information into that sequence. Open the Event List on that track, click Filter and Notes and look and see if there is some pitchbend going on.

That was my problem, I had a midi gizmo online that was periodicially sending random pitch-bend information. I thought I'd never track it down!
