Default [6.34] Incorrect dither when rendering multiple bit depths (FIXED)

As part of my mastering workflow I often render 16 bit and 24 bit .wav files of the same song so I was pleased to see that this can now be done in one step from the render window. However, if I select the dither check box only the primary file is dithered correctly.

If the primary file is 24 bit and secondary is 16 bit only the primary file will be dithered (at the correct level) and there will be no dither in the 16 bit file.

If the primary file is 16 bit then both files will be dithered at the 16 bit level.

I was under the impression that the dither level should be set for each file individually rather than just the primary format.

This is using the 64bit version of Reaper on Windows 10 version 20H2.

Yes, confirmed. Dither is parameterized to the primary render format. We’ll fix this for the next build.

This is now fixed in the current prerelease build, if you’d care to try it.

Many thanks for a speedy fix. I've only tested it in one scenario so far (24 bit primary and 16 bit secondary) but it appears to work fine.
