MIDI output of unfold and tremolo repeats are different?

[sereliya at yahoo dot com]

Dear LilyPond users,

I have been having a strange problem where the MIDI output

of tremolo and unfold repeats are not the same (durations).

Has anyone been having similar problems?  Any pointers as to

where to start looking for correcting this would be greatly

appreciated.

Many many thanks in advance.
