I am playing around with the Viena SoundFont Editor (Versions 0.935 and 0.940) and I was able to add smaller audio samples to a newly created soundbank. When I am trying to load a large sample > 400kB Viena shows a dialog with the error "File could not be read". I have not found anything about an upper duration or file size limit in the documentation. I also wanted to see if the wav-file was of a non-standard format (they were created under MacOSX), so I tried using an .aif-sample as a starting point, converted it to wav using ffmpeg and I then tried to load this one into Viena, but it failed with the same error message.
Could anyone help me towards a solution, please?
