Stefan, The file played perfectly here, i.e. it played perfectly when it is all within BiaB. All I can think of is that the problem is between your laptop and your peripherals. How are they connected to your laptop? Are both plugged directly into it? Are you using a MIDI hub? If so is it a powered hub? Are the USB chords good?

Maybe you could upload an audio version of the song so we can here exactly what you are hearing?

Were the MIDI and audio tracks all generated from BiaB or did one or more come from another source?


The fitness trainer asked me, "What kind of a squat are you accustomed to doing?" I said, "Diddly."
