Hey guys, I'm using Sibelius 7 and Vienna Ensemble PRO, which is running on a separate machine as a server. Sibelius is using the latest VSL house style and my playback configuration is set for Vienna Special Edition PLUS. I currently own VI SE (+ Extended) and VI SE PLUS.

When my sibelius instruments send data out to the VI running in VE PRO, I notice that the Expression controller (which I generally set to Velocity x-fade) changes a little on every note, and in many cases it is a noticeable dynamic change. Is something configured weird or is this some strange feature ? If this is a Sibelius related issue, does anyone have any experience with this and what can I do to correct it ?

This happens when starting a blank score and creating a blank VE PRO instance, no custom configuration.

I ran into a similar issue last night when automating with a controller connected to a 32bit VEPro slave running on an MBPro, using the VEPro Event Input Plugin, in a channel in Reaper on the host machine. This setup worked perfectly on the first recording, but I now get a "jitter" on subsequent takes in the form of repetitive, nonsense midi messages. If I mute the VEPro channel in the DAW, I can turn off this effect. I had thought that I was in some type of midi 'feedback loop' but wasn't sure and didn't have time to troubleshoot further. Once I scrapped this feature in VEPro and ran my controller and automation from my host DAW everything went back to normal. Not sure if this is the same bug as Nick's but thought it might be possible. I originally moved my controller from my DAW to the slave to free up CPU cycles. Any help from the VSL folks or anyone that's run into a similar issue would be greatly appreciated. :)


DAW = Reaper on Win Vista 64, Core2Quad, 8gig Ram
Slaves = MBPro's on OS X (Lion)

Try in Sibelius 7, under the Play tab to check off Live Playback.

Also under the Play tab open Performance and under Style it has expressivo by default. I use Meccanico instead.

This 2 adjustments make the expression faders move all the time up and down and I have them checked off by default when I work with external libraries in Sibelius, for me they are tottally useles.

I hope this is what you are talking about.

good luck
