The Sibelius Forum

Whenever I have any large ensemble score open (pretty much anything more than 3 staves at a time), partway through playback random instruments will simply switch to other playback instruments. Once it happens, there is no way to fixe the instrument. Any suggestions?

Hey Mike,

I'm running Windows 11 OS Build 22000.527 and Sibelius Ultimate 2021.12 Build 580. I generally use sibelius sounds, but the playback issues occur even when switching to midi sounds.

I've sent you an email with a sib file attached; the playback issues start in mvt 2 m. 102.

Thanks,
James

This recently started happening to me as well, was wondering if you ever found a solution.
