Hallo Jazzmandan,

thank you for your answer! I use the DXi-Synth, supported by BiaB.

Meanwhile I resetted to factory settings. After I've done that, the problem starts in the measure 20, not in the measure 5 as before, but as you understand that's not much of a help.

Since fj4_145 is not a popular song and you may not hear the mistakes right away, please compare it with the notation window of BiaB.
