Note durations when playing back from bach.score

[acousmatician]

Hi - I am new to Bach, so I have probably not understood something.

When playing from bach.score to a MIDI device, it seems that the notes to not play for as long as the score suggests. They seem to be about 2/3 the correct duration, with a rest (silence) until the start of the next note. For example, a note that is 12 beats long (three tied whole notes) will play for 8 beats, then four beats silence, then the next note. Or a dotted quarter note will play for one quarter note, with one eighth note rest, before the next note.

If this perhaps due to a setting I have missed? (The bach.score was read directly from a musicxml file generated by Sibelius)

Thanks

Update - I have changed the durstretch option to 1.5, and the score now plays as it should. Still, I am a bit puzzled. Perhaps it is a Sibelius problem?

Hello, this looks like an issue with scheduling.
Are you sure you have Max's Overdrive on? If not, you cannot rely on accurate scheduling.
Can you please put your object in the best shape for realtime usage by sending a "realtime 1" message?
That should be the best bach can do...
