Cannot export to .wav

[FidessaPiano]

Hello.

I recently downloaded LMMS after reading rave reviews. It IS impressive.
It does everything I need and I have mixed a great project.
I shall be making a sizable donation...

HOWEVER, I need to be able to capture the music, but, exporting to .wav isn't working.
The dialogue screen just sits there for a few seconds with the progress bar at 0 and then disappears, creating a file of just 1KB.

Please help, as I am currently doing an assignment and need to convert to wav, so, that I can then use my conversion software to send in mp3 files.

In hope.

That's weird, what you're trying to do, seems exactly what I do. Export to wave, and then depending on to whom I send the mp3, I convert to 320kbps mp3 (or lower for those who want a smaller file), with audacity.

Whats you OS and hardware specs ? Did you change any settings in the export window?

I always only change the sync to best.

Jubiiiii.. :p

but, exporting to .wav isn't working.

Sob.. :|

The first thing we need to make sure is that you actually can export
so from a completely new project:
Add a few notes in the trippleOscilliator and go to export
Now the export is currently somewhat 'dumb', because choice need to made twice
In the first popup

choose Wave
(the arrow actually point to ogg, because the picture is from a help i wrote for the exact opposite :)
But you chooses Wave!

In the second popup

make sure it again shows wave, and then do not make any selections at all
Just press START
Does that also fail?
If so
please post your:
* OS (+service-pack-ver)
* lmms vers
* hardware specification (ram & soundcard is the most imortant)
* lmms sound device chosen
* if any -screenshots of error
* if relevant, demo mmp

I also have this issue if the project contains any change in time code. Any other instance, it works just fine. But as soon as the export hits a Time Code change during render, it will stop, and it will only export the previous section of rendered file. Also does this under .ogg as well.

any change in time code

if you with that mean time-signatur, then i cant reproduce.

...or just point at the relevant issue on Github: https://github.com/LMMS/lmms/issues/2030

It probably doesn't always happen, but with the right time signature change it will. I didn't check the code, but it's something like this: The calculation of ticks (or bars) left to export assumes the entire song is in the current time signature. So, when you put a change from 4/4 to 8/4 in bar 10 out of 16 it goes like "8*10... that's like way beyond the last tick, STOP". But you've actually just played 4*10 at that point.

OS Windows 8.1 64 Bit
LMMS Version 1.1.3

There is no error code, just the bug. Not that hard to replicate the bug, just find an MIDI with multiple time-code changes.

LMMS don't handle time signature changes to well. I always change the time signature to the best suitable one for the whole project.

unfortunately softrabbit told you how it is.
The changing i used did export, but that was a fluke, current version does not export time-changes
