Hi,

I've been able to reproduce, and have MOTU reproduce, and another Digtital Performer user reproduce the folling issue:

My system is a 2013 MacPro running Mojave with a PC Slave.  I'm running VEP 7 (not the current update)

I am reproducing the issue using the VEP MAS plug in a 16 instance, 16 channel template not actually connected to VEP instruments locally and on the slave.  Beachballs are frequently appearing when I toggle from one channel to the next.  Reordering midi or audio tracks induces a hang with a beachball.  Video demo here:  https://cdn-data.motu.com/django_prod/techlink-attachments/152540/IMG_0505.mov

Here are some video demonstrations that shows how using the VEP MAS plug in a 16 instance, 16 channel template causes sluggishness and a beach ball when moving an audio track.  The other video shows how using Kontakt instances (same configuration) does not cause this issue.

Perhaps it's bad with VEP MAS instead of AU because of the number of auxiliary audio outputs and/or MIDI ports that VEP MAS exposes.  

With AU version of VEP, the issue has improved greatly, no beach balls.  Would love to have the multi-port feature that the MAS version offers but it seems like I need to use the AU version for now.

Is this addressed in the latest update?

Thanks,

Dave

How many MIDI ports have you got in the VEP plugin settings? Is the issue improved with a single MIDI port?

Hi Martin,

As for me, my testing involed only one port.  My template involved anywhere from 2-8 ports per instance.  My new template now uses the AU version of VEP and the issue has dissapeared.  Would much rather have the multi-port feature obviously.

Thanks,

Dave

We are mid contract Dave, so cant yet update the plug. Will do when done!

I appreciate your report Dave! Thank you. Shall wait to update then.

Hi guys, 

Can you please tell us which version of VE Pro 7 you are using, exactly?

Also: How many VEP plug-ins with how many outputs each?

Is there any miminal reproduction scenario that we can set up here?

Thanks, 

Paul

Love you guys! I knew you would get on it. Thank you Paul and Martin.

Hi,

I can also confirm that I am having the same issue as others. I am running 9 Instances of VEP7 split over two PC Slave Machines, with about 190+ Stereo Outputs coming back into DP.

The time it takes to add a Midi or Audio track is about 20 secs, and moving tracks and folders also takes about the same time. As soon as I disconnect the VEP7 instances, DP works as normal.

I have a tech support running with MOTU and glad to see others have raised this too. I thought it might be something to do with my template or the number of outputs I need to run it.

So pleased to read that VSL and MOTU are communicating with each other to help resolve this.

Hi, 

Martin Saleteg (MS) heard back from the DP team. This issue should be fixed with the next DP Update (10.12), expected in the next few months. 

Best, 
Paul

Great news!  Good to know I wasn't the only one experiencing this issue.  Still, I'm amazed that I was the first one to report it (or so it appears).  Perhaps my template or use of the plug is unordinary.  Regardless, happy!
