instruments dropping out when exporting

[peterivers2]

Hello, I've been having problems with instruments dropping out when I export the score to an mp3 file, what is this about? I haven't had this problem before, thanks

Hi, before we attempt this one, can you tell us the exact version of sibelius Ultimate and the exact version of MacOS, please?

[peterivers2]

Hello, thank you for your reply,
the operating system on my mac is Sonoma 14.4.1 and the Sibelius Ultimate version is 2024.3 build 3166. Thank you.

Ok. That's good. Can you screenshot the playback devices list and the audio engine options dialogs, please.
Did anything change before this started happening (updated programs or drivers etc). Is this recent change or has it always done this since you updated to 2024.3.1

Hello, the problems started this year together with license renewal for which I had to request assistance from Sibelius support twice. Also, sibelius not responding to dynamic markings, octave transpositions, etc. I tried uploading the screenshots but it won't let me it says they files are too big and when I change them to pdfs or heic it says they have the wrong file extension. Is there another way to upload them, I also tried to upload the Sibelius.sib score but it wouldn't let me. Please advise, thank you.

You are aware that this isn't the official Sibelius forum? It's an old, almost moribund site that's very fussy about attachments. Only 3 people answering questions and I can't help on this one.

Official Sibelius chat page would be the best place to ask - you'll find Mike on there as well!

Nope, I didn't know, thanks for the heads up, cheers!

The OP did post on the official site and got immediate responses! No surprise there, then.

The 'problem' was that hairpins had been duplicated with MIDI messages to reduce volume to zero, but no MIDI messages had been inserted to bring the volume back up.
