Hello dear users !!!
As a melody instrument I connected an external sound module (Korg Kronos) via USB (as a MIDI connection). The audio out of the Kronos runs via a jack cable into the input of the PC's sound card.
The real tracks from Band in a Box serve as accompaniment.
The song is finished, you can hear all the instruments when you play it.

I now want to export the song to an audio file.
Unfortunately, Band in a Box writes to me when generating an MP3 file
an error message (Rendering Failed).

What do I have to do that you get from 2 different sources
can generate an audio file.
Or do you have to use the RealBand program for help?

Thanks for the information!
