Thanks DM
Using ASIO
I have tried all latency settings (knowing that sometimes too much is also bad!) and latencies/buffer sizes give glitches
I even tried the Max setting - giving latency of 0.2 seconds!!! - and that still had glitches

Hello, I have the exact same problems. Large scores cuts of samples and pops and clicks even though I have 8GB ram and it's at least 3 of them availible when the entire sample library is loaded. I have the latest Sib-update, a dedicated SATA-disc for the library, using ASIO with an ESI1010-soundcard. I'm afraid the problem might not be VSL: Sibelius 6 has huge amounts of flaws when it comes to playback and stability. I had to switch from my Macbook as main working enviroment since Sib6 crashed all the time even though I reinstalled the OS several times. The playback is also unstable there, even with Sibelius own library. At this point, I have no idea what to do with my setup, this just doesn't work.

Hello Snattack!
These kind of problems with big arrangements may have various reasons.
Maybe your CPU is overloaded. If this is the case, raising the buffer size of your audio hardware driver may help.When lots of instruments get streamed at the same time, maybe your hard drive can't come up. In this case it may help to divide your sample content on two hard disks. Don't forget to update your Directory Manager after that.
Best regards,

Although you have 8GB of RAM are you running 64 or 32bit W7 - if the latter then your still only able to access just over 3GB of RAM.
What do you mean by large scores? I have 64bit and 12GB of Ram that just about copes with 30 staves/instruments each with around 10 articulations roughly half of which are performance patches. Although I'm also running MIR. Whatever your problem it's not SIB6 which works flawlessly for a lot of peaople running VSL.
What CPU are you using?

I think the issue for those of us moving from XP to Win7 (rather than Vista) is that Win7 is not as resource efficient as XP. As Andy pointed out: not a great surprise given the 7 year gap between OSs and therefore the assumed Computer capability. Essentially I was working on what for XP time was an extremely powerful machine but for Win7 era just a decent workstation.
It IS still strange that the issue appears to be with disc streaming rather than CPU - well certainly in my case. The CPU does not get beyond 40-50%. And changing buffer to even the highest makes zero difference (all of this a summary of my posts above)
What has improved the situation for me - although nowhere near up to the same level as on XP - is to stripe two discs (I did so on Win7 rather than at the BIOS level but I may go back and do that in case I get any better improvement). This has meant that rather than before, changing buffer size actually makes a difference so I would suggest that the disc streaming was the issue.
I would recommend trying that - after all discs are extremely cheap now.
It's just odd that Win7 does not seem to stream from disc as effectively as Xp!

Hello, I'm using a brand new Intel i5 processor, Windows 7 x64 and 8gb of ram. When reading the resource manager and playing back the score at the same time, it's not using nearly the bandwith the harddrive can take, but I'll move the library to another disk and try anyway. When it comes to ram, when the large patch is loaded, it's still 3,5GB left. I've tried all avalible buffer sizes. Also, today the problem showed up on a string ensemble piece, which consists of 5 staves, so I guess the problem isn't the score size. The only conclusion to this so far is that the sound card might be the problem. I have the latest drivers. What soundcards are you people using? When it comes to Sibelius and playback, I haven't yet met many people for whom it works "flawlessly". It's filled with bugs and bad performance, but this is another discussion.

Just another thought - are you using altiverb and do the clicks happen on rits and accels?

Update on the poor performance in Win7
I downloaded a sequencer (Reaper as I don't have the cash for the others!)
I have imported the same scores with which I was having playback issues in sib in Win7 with the same number of Altiverbs FX etc and Reaper has NO problem playing back..... zero glitches
I still think something's amiss with the Sib/VST/Altiverb combo in Win7.... at least on my PC!

Following the thread above - Having struggled away composing with almost zero reverb (lovely! - but not too much an issue as it was all eventually played by real live musos!) I had a moment of clarity having tried the MIR demo. This worked fine with up to 20 instruments.... which re-ignited my "something's wrong with sibelius not my PC" argument!
As I was using LoopBe with MIR, I tried the same with VE totally removed from the Sibelius playback and I can now playback massive scores with 4 Altiverbs with no trouble whatever!
So for those in this thread having similar problems may I suggest the meagre outlay to get some virtual midi cables!
