Vienna Ensemble no sound while running Sibelius 5.4.0

[Cgerhold]

I just migrated my mac from snow leopard to lion 10.7.1 and it's been giving me headaches. I can run and hear sample sounds in 'ensemble-64bit' standalone mode okay. My problem is when I open Sibelius 5, setup my devices, load the sample I cannot hear anything. The volume mixers move up and down when I press a key like normal, but i can't hear anything. There is no sound when a note is played on the manuscript, and there is no sound in the vienna ensemble menu. Everything is routed as it should be. I don't believe it's a routing issue but rather, I think it might have to do with the directory manager or something. I could get the sounds to work for a while...temporarily. they worked fine after I deleted the folders in directory manager, then added the files from where they are stored. (separate HD). This however seems to be a temporary fix. Are there some setting's that is inhibiting them from being heard? Lion osx 10.7.1 MBP 2011 16 gig-ram 2.ghz quad core intel I7

Hello Cgerhold!

I'm not sure, if I understand your problem!
Does it work again now? Why do you think it works only temporarily? Is it only Vienna Ensemble that doesn't make a sound, or do you have the same problem with other AU-instruments too?

Best regards,
Andi

Here is the issue. When creating a new score (sibelius 5.4.0) and loading the sounds, it works fine for the first time. I can hear the sound, both in the vienna ensemble and in sibelius. The problem is when the score is later reloaded there is no sound. The instrument is loaded correctly and i can see the volume mixer moving up and down, and the patch is present, however there is no sound. I find it extremely weird. Another experiment I tried is loading an old score with pre-saved vienna presets. no sound. I close that project (and without restarting sibelius or vienna ensemble) start a new score and load new vienna presets, then there is sound. But only for that one time. If i save it and go back later. there is no sound. It works fine all the time in standalone mode. I updated everything vienna ensemble and re-installed sibelius 5.4.0. However, i cant hear other au unit sounds either. Midi works fine

Hi Cgerhold!

This is really weird. I haven't heard about such a problem yet. If the same thing occurs with other AU-instruments too, it probably has nothing to do with our instruments. Maybe the Sibelius support team can help.

Best,

Yea it was a really weird problem. But I figured it out! What was happening was under "effects" Sibelius 5 was loading "Altiverb 6" under master effects by default for some strange reason. Altiverb 6 and the new Lion osx 10.7.1 dont play well together. So i'm waiting (and the rest of the world) for Altiverb 7. I just changed the effects to 'none' and voilà. beautiful sounds!

Thanks for letting us know. I'm glad, that you found the source of the problem.
