Hi! Could you tell me how to convert my midi tracks to wav with MuLab free ?
When I try to do it, there is nothing in the audio file...
Thank you!

First off, if you're importing MIDI files into MULAB Free you'll likely trigger the multi-channel per part threshold.

Second, MIDI files contain no sound - you need to supply the sounds some how. MULAB comes with a vast array of built in sound generators you can choose from and there's an even wider array of free VST plugins available (see the KvRAudio plugin database). So that part you'll need to decide on.

Once you have that set up, it's "Session", "Mixdown Audio" (which I guess you tried already).

Thank you for your answer.

Finally, my problem was the wrong position of the arrows on the timeline (start / end)!

Don't you just love it when it's something like that?
