Barcheck failed when MIDI is enabled

[Helge Kruse]

Hello,

I am copying a manuscript that uses volta repeats. The first measure is a upbeat (partial 4).

I get the expected result. I looks like the manuscript. I also want to use the MIDI playback to get an impression how it will sound. Unfortunately I get

PartialRepeat1.ly:65:31: warning: barcheck failed at: 1/2 <d b'>4 <b g'> r8. <d b'>16 |

if the MIDI output is enabled.

Why do I get the warning only for MIDI output and how can I avoid it?

Best regards, Helge
