I’ve found the following: If you load a project and do an export, it will work, but before doing another export, you have to push once the Play button. If you don’t then you’ll end up with the silent file.
If you press Play after an export, the time/bar display will jump to some strange big number, but disregard this, simply press the Rewind button to correct this. But mind you, just pressing the Rewind button will only heal the time display, but not the start position of the next export. So you always have to press the Play button, otherwise the next export will be silent.
So you see, this whole area is buggy and what I’ve described is just a workaround for you, sure we will fix this all up.
What I still can’t reliably reproduce is that what byronhawkins describes, that the export only starts at the current playback position. It only happens rarely to me, but sometimes I find that in an exported file after long silence suddenly sound does come out, but can’t find any recipe for reproducing.
At Byronhawkins (and others), can you always reproduce this? Could you maybe make a simple Piano project with just a few bars and post here the project along with the exported file?
Btw, I’ve found another issue in that exported files always miss the very first note.
