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?


I'm no longer allowed to go caroling at the psych hospital.
I guess Do You Hear What I Hear was a bad song choice!

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
