Crossfade Tracks error

whbjr · July 19, 2015, 8:06pm

Interesting error message! Before attempting Crossfade Tracks, I used Adjustable Fade on a track - does Crossfade rely on Adjustable? Was Crossfade “blocked” from setting the options on Adjustable because I had already set them via S-Curve In? Is this a bug, or a feature? And, what about Naomi?

Win

EDIT: When I clicked “OK”, it brought up the standard Crossfade Tracks box, and all worked normally. Using it a second time did not cause the error message to occur.

Yes “interesting” error message. The message is referring to setting in “Adjustable fade” and has nothing to do with “Crossfade Tracks”.
If you find that you are able to reproduce this behaviour, please do let us know how

Always a good request! Here’s how to reproduce this error:

Start Audacity (creating a new project), generate two tracks
Select a portion of one track, and apply “Adjustable Fade” - no error
Select a portion of two tracks, and apply “Crossfade Tracks” - error! “Could not update effect” (plus details). Click “OK”, and the options dialog for “Crossfade Tracks” appears, and the effect works as expected.

Similar Error:

Start Audacity (creating a new project), generate two tracks
Select a portion of the tracks, and apply “Crossfade Tracks” - no error
Select a portion of one of the tracks, and apply “Adjustable Fade” - error! “Could not update effect” (plus details). Click “OK”, and the options dialog for “Adjustable Fade” appears, and the effect works as expected.

Note the key element of Step One: This only happens after freshly starting Audacity. This error occurs once per “instance,” then both Adjustable and Crossfade work without error… sort of. Trying it again, it seemed to “remember” the cause error, even when exiting and restarting Audacity. (Exhaustive testing is hard!)

I’m not able to reproduce the error.
What version of Windows are you using?
Which version of Audacity?

whbjr · July 19, 2015, 10:43pm

Windows 7 Home Premium SP1
Audacity 2.1.1

This might be important: I downloaded the Zip-file version of 2.1.1, and dropped those files on top of the previous installation. I’m sure I’ve exited Audacity multiple times, but I don’t think I’ve rebooted since then.

Reboot your computer, then with your file explorer, go to:
Users<user name>\AppData\Roaming\Audacity\

Delete the files:
audacity.cfg
pluginregistry.cfg
pluginsettings.cfg

This will reset Audacity back to day 1 defaults which should remove any incompatible settings that may be causing the problem.

Then start Audacity and see if the problem is still reproducible.

That worked - no more fade-related errors. Also, no more Saved Presets for various other effects so I put back my “broken” config files, and I’ll live with the error messages.

I sometimes see a message like that once per session and once per effect if I move from one version of Audacity to another previous version and back to the version I tried first. I’ve got a similar problem right now on Windows 7 in 2.1.1 release.

Did you or do you have more than one copy of any effects in the Effect Menu?

If you still get this message first time in each Audacity session, can you attach the pluginsettings.cfg and pluginregistry.cfg? Please see here for how to attach files: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1
