Transpose Problem

Hi Everyone,
 
I am involved in a vocal harmony project and sometimes, to expedite matters, I just send everyone their vocal parts individually to learn. The female parts are too high for me so I have been using the "transpose audio" feature to buy myself of whole step or so. However, it's functionality is very erratic. (I am using Process>Transpose>MPEX Solo Instrument Single Voice / Transpose Audio.
About 25% of the time it works. The rest of the time, the bar graphic shoots over very rapidy and nothing changes pitch-wise. In fact, the "Undo" and "History" menus don't even show it as an event. A couple of seconds later I get a message that says "Could not save complete recording. Audio disk may be full" and nothing will make the transposition happen after that.
I assume I'm doing something wrong but as I follow the same procedure every time, I cannot understand why it succeeds sometimes and not others. I really need this tool and any help would be much appreciated. In fact, if there are any other superior ways to transpose a vocal, I'd love to learn. This does not have to be performance quality and a little "chipmunk" is OK. It's only for people to learn their parts. The quality isn't hugely important as long as it's listenable.
 
Thanks, everyone.
 

Hallo.
 
I'm not sure what's going on here.  If I select a clip or track, and use process>transpose, it opens a window. You can choose various "type"s - radius vocal etc, but I don't see MPEX.  Is "Transpose Audio" ticked each time?
 
I tried it a few times up a tone with the settings I had, and it sounded "chipmunk", but it worked.
 
Am I missing something.
 
What version of Sonar are you running?
 
VVocal may be an alternative, but Process>transpose should work for what you want.

mpex isn't part of recent versions of sonar afaik, it's from previous versions.  the radius options are the newest.  

on a different note, i can get transpose to work, but formant scaling is always grayed out. that the same for everybody?

@nick123 - What version of Sonar are you using?  Post your specs in your sig.
 
@swamptooth - formant scaling is greyed out here too.
 
I'm off to bed now, but I will pop back tomorrow.

Funny that neither help nor the manual have anything to say about the Type field in the Process->Transpose dialog box.

nickl23 - Audacity is a stand-alone mini-daw but the Sonar function is more or less identical, maybe better with the different types, so I'd forget about it.

Fair enough.  Glad you got it sorted, whatever it was.
