  • And this issue only occurs when hosting Play inside VE Pro?


  • the only time I've noticed it is with Play....as I just started using Play with it since the last update... I haven't had a chance to do any serious testing with it yet. Using the 64 bit server, I have maybe 3 or 4 vienna inst loaded and then just EW pianos gold, using a light patch. a perfectly quantized chord comes up and it literally sounds like a rolling chord so I imagine there has to be like 40-80 ms between notes even though they should be simultaneous. I'll bounce some tracks later to test the exact timing problems. I'm on a gigabit network that I don't share. Thank you for looking into it. Let me know if you need any other info. j

  • I'd be really curious as well to see if this occurs when hosting PLAY directly in Logic...

    Please let us know how it goes!


  • I think I found the culprit.... I had my process buffer set to "large" in logic...changed it a couple of days ago as i was getting tons of errors for some reason. put it back to medium and timing seems to be on again. Does that make sense?

  • Yes, very much so. VE Pro pretty much relies on having the process buffer set to medium.


  • Is anybody still experiencing out of sync bounces in Logic? We've been looking into this but are so far unable to reproduce using v4.1.7384.


  • It seems fine here, Karel.

  • I've been so busy with projects that I haven't been able (or willing!) to do any software updates since I first posted about this issue.  I'll update around end of the year and check to see if the issue still exists.

    It is 100% reproducible & consistent for me though, but the upside is that I know how to work around it... all I have to do is set the VE Pro buffers to "none" when I bounce and everything's fine.  The problem though is that my template has 14 instances of it, so that gets to be a chore...


  • Which version of VE Pro are you currently using? I would seriously recommend updating to 7384. Should you run into any trouble (which is very unlikely), you can just install an older version again without issues.


  • I'm at 4.0.6150.  I've been in the middle of working projects which are heavily dependent on VE Pro and other than this issue it's been rock solid, so I didn't want to risk upsetting the apple cart mid-project ;-)

    I will give 7384 a try ASAP.

    Thanks Karel!

    P.S. I was just in Vienna a few weeks back  - wish I had time to stop by!


  • Hi there - I'm a Logic Pro 9 / VEP user and am having the same problem with latency when bouncing regions in place. Since I have so many instances of VEP running, I was wondering if there was a way to set Logic (and / or) VEP to bypass the buffer settings on bounce. It would be very time consuming to do this every time as I am always bouncing tracks in place. I'm running build 8008. Thank you!

  • Hello,

    There are 2 workarounds for this depending on which version of VEP you have installed.  The easiest is to simply turn off Logic's delay compensation altogether (in Logic's preferences) just before bouncing - then turn it back on afterwards.

    The other is to set your VEP plugin buffer to 'none' - this eliminates the dead space at the beginning of the resulting bounce file.  I think this has been fixed in later versions - not sure off the top of my head.

    Hope this helps!


  • I'm running build 8008. Turning off the buffers before bouncing works. But I would like to know if its possible in VEP (or in a future version perhaps) to give the option for VEP to automatically turn off its buffers only when bouncing in place? The main convenience or me is that I like bounce tracks as I compose and this would be a great time saver. Also since I have so many instances of VEP running in a huge Logic template of over 200 tracks, I would not be able to turn them all off. I would love to run without buffers at all, but doing so makes my cpu spike. As for the other option, Logic's delay compensation altogether / that doesn't seem to make a difference on my system. Thanks! =)

  • Would like to feature request a way for VEP to 'AUTO TURN OFF' buffers ONLY when bouncing midi to audio, then reactivate them after bouncing. Is it possible to do this or only doable manually? Would be a great time saver. cheers!!

  • Hi I wanted to bump this in case anyone has any helpful input. I'm running Logic 9 Pro with three slave PCs running all my samples. I have about 30 instances of VEP running in my Logic template. THE ISSUE: When I bounce audio in place within Logic - the audio renders slightly late to where it should be. I always have to go in and move it back to the correct position every time. The only way to make it bounce perfectly is to disable the VEP buffers within Logic. Then it bounces perfectly in the correct position. But to do this every time is a bit time consuming since I frequently bounce audio in place. So my question is... is there a workaround for this, or is it possible in a future version of VEP to have the option of making the plugin disable buffers (on bounce only)? I would disable them all together but then my CPU spikes in Logic, so thats not an option for me. Thanks!

  • Hi,

    As mentioned above, the easiest workaround for this (instead of turning off the buffers in each VE Pro plugin) is to just turn off Logic's Delay Compensation before doing a bounce in place.  It has the same net result.  I need to check and see if this has been resolved in later versions...


  • The main goal - or hope I should say is that I won't have to turn anything off and then on again... I did try turning off Logic's Delay Compensation and it didn't make much difference. The only way in my setup to do a perfect bounce is to turn the VEP buffers off. But it just gets time consuming with my method of working since I frequently bounce my midi as I work. Was just curious if it would be possible to have the option of making VEP auto turn off buffers when bouncing, but I'm not a programmer so I don't know if that is doable.

  • I hear you - totally get your frustration as I have a similar setup.  So turning off Logic's delay compensation didn't have the same net result?  It does for me... either method eliminates the extra space at the beginning of a 'bounced-in-place' region.  I join you in hoping for an eventual fix for this!

    Take care...
