Hi guys, same problem here!
The loaded instances take 45-50% of cpu only on idle.
Any news about this?

Thanks

Hi all,

I also have big problems with the synchronous pianos, impossible to use the different microphones as I should normally be able to do. I use the Vienna Ensemble. I have a very powerful PC since it is also used for gaming, and I have no problem with games: AMD Ryzen 9 5900x / 64GB Ram. I have already made the settings proposed in other posts to improve things, but as soon as I put 4 or 5 microphones, the CPU is overloaded. There are major optimization issues.

I am having the same issue.  I am using the Synchron Harp, Strings Pro and Oboe d'Amour on a pretty large project.  ALL of my other AUs are playing fine and without any issues except for the Synchron Strings Pro.  It is bogging down the system badly and it's so frustrating.  Since switching over to iLok this has been the one constant CPU issue with VSL and it's really frustrating.  Any news or updates would be great.  I have tried all the things people here have mentioned and still no resolution.

Thanks,

Seth

MacPro - Latest version

128gbRAM, separate 2TB SSD drive solely dedicated for only VSL products.  Logic Pro - latest version.

Same problem here. Its strange because I was doing very well with the I-lok version of the libraries until I reinstalled them on the new M1 MacBook Pro. The libraries are now taking a lot more CPU than before and of course it should be the other way around since the computer specs are now higher.

Hope this gets solved soon. Im working on a project that needs the VSL libraries.

I'm having the same issue. I just installed Synchronized Dimension Strings on iLok and can only play 3 or 4 notes before getting 100% CPU and dropouts.

Hello everybody,

Sorry to hear that you are still experiencing these issues, after all the fixes that were implemented since spring.

A few things to check:

- Correct formatting of your SSDs: ExFat will deliver VERY bad performance!
- Did the PRELOAD SIZE in your Database Settings change with the switch?

If that doesn't change thinks: Please send us exemplary projects along with description/reproduction information and the support file you can create with a click in your Vienna Assistant!

If we can reproduce your findings, we can find out more.

Best,
Paul

Hello. Which SSD type is recommended for Dimension Strings I, Sy'd Historic Winds and your free stuff? Is SATA III SSD good enough or can it slow down performance if for example all sections of DS are used? My CPU supports NVMe with PCIe Gen3 X4.

BTW, I have CPU spikes too (AMD 5700G) when using DS. The libraries are on HDD now because I just wanted to try them. After reading previous comments though, I'm worried that the problem will remain even after putting them on an SSD.

Hi Paul, I am having the same problem of very high CPU usage when using the Synchron Player. Simply playing the instrument itself peaks the instrument.

I am using the version 1.1.2063 (latest available on my download) of Synchron on Win 10 latest drivers and 16GB Ram on i7 processor. I use an internal SSD 2TB NTFS format. 

Please help fix.

Since it was mentioned earlier:

We have followed up on reports and at least for some of these cases, a common denominator seems to be Focusrite audio hardware. For some reason, those audio interfaces (or their ASIO driver) do not play nicely with the Synchron Player. Unfortunately, we don't know why at this point.

Kind regards,
Andreas

Same problem here.

I am running the Synchron Player for the first time, stand alone, with the Hello Free Instruments. All instruments seem to work as expected except for the Fujara Flute, which puts heavy load on the CPU.

I have an RME HDSPe Asio Pro internal soundcard. Win10, AMD Ryzen 5000.

Playing one tone only, there is a proportional relationship between the RME ASIO driver buffer size and the CPU load, as follows:

Buffer Size/CPU Load (%):   32/100(overload, no sound), 64/63, 128/38, 256/19, 512/10, 1024/5

Another interesting observation relates to which microphones in the mix that are active.

Having any or all of the following microphones active gives a very low load (eg 2-3% at buffer size 64): Main, Main-C, Surround, High, High-Sur.

Only the Mid and Close microphones, when active separately or together, contributes to the high load (61% at buffer size 64)!

Could that information get you any closer to finding a solution? 

Yeah the free Fujara Flute is out of control with the CPU.  I have plenty of Synchron libraries and none of them are like this.  On Windows 10, RME UFX+, Intel 9900K.

I don't know if it's related to everything else, as the rest of my Synchron libraries act normally.  Same experience as Chris- only the Mid and Close microphones are going crazy.

Here's a screencap of what's happening:

What happens when you switch off the additional reverb?

What happens is that @Dietz gets a gold star! 😃

The algorithmic reverb is the culprit. So the follow up question is: why, and how do you fix it?

Hi! Thank you for confirming! We'll investigate further.

Best,
Andreas
