Synchronized Dimensions Strings causing random but continuous -9173 ProTools errors

[Alessandro Panella]

Hello,

I'm experiencing lots of -9173 error in ProTools caused by VSL Synchronized Dimension Strings, as can be ssen in the attached picture.

I'm working on a MacBook Pro with M1 Max processor, 16Gb RAM and the library is on an SSD drive. The CPU load of the session is about 30 % (I have a mock up of a Mozart concerto, with VSL strings and piano-woodwinds-brass from other manufacturers, namely Moddart Pianoteq, Spitfire BBC Symphonic Orchestra, East-West Symphonic Orchestra).

When I press play, the session runs for some seconds and then I get the error message, referring to one of the 5 open VSL plugins.

Any clue about how to solve this?

Thank you very much.

Hi Alessandro,

I get this quite a lot also with CPU load around 30% - mostly it's just irritating. If I hit "save" and then "play" (often I have to hit play a couple of times for things to right themselves) I'm back to normal.

A few things that seem to help a bit (for me, anyway) - these are very obvious but sometimes the obvious works!

1) If you're working only with MIDI, as it says, try setting a high buffer size. I often go with 1024

2) Unload unused samples from RAM.

I believe the VSL team are working on Pro Tools versions of various things so hopefully we'll see some improvements soon. I also get various other issues, such as PT failing to clear all sources from MIR when I close a session. However all these issues are, for me, irritating rather than incapacitating. Fingers crossed improvements are on the way.

All the best

Nick
