VE Pro doesn't playback Kontakt consistently when used on DAW machine w/ Logic 8.0.2?

[JT3_Jon]

Hello,

I've run into a snag with VE Pro and was wondering if anyone else has experienced this problem. I'm running an instance of Kontakt 2 in VE Pro on my Daw machine w/ Logic 8.0.2 and OS 10.5.8, and can get it to play & record PERFECTLY! However, it will not playback what I recorded consistently UNLESS I keep the "record enable" button active on the tracks I've already recorded (sometimes it will playback without it being in "record enable mode," but eventually it will stop playing and the only way to get it to play again is to click the "record enable" button on a track). Obviously this isn't a work around, as I cant keep VE pro tracks record enabled all the time (in logic, you only record enable tracks you're going to record on) but I find it interesting how having record enabled will cause it to playback correctly everytime, yet once I turn it off it will not. 

Everything runs PERFECTLY on my VSL only slave, when running Spectrasonics Omnisphere on my slave as well as on my DAW, so it seems to be a problem with VE Pro and Kontakt specifically. I dont know if this same problem would occur when running Kontakt on my slave (I cannot test it because I do not have Kontakt on the slave). But like I said, I have run Omnisphere fine on both a slave and on a VE Pro on my DAW computer, and it plays back everything correctly. I've tested this in both my autoload and a fresh Logic 8 song, and this problem occurs in both when playing/recording Kontakt. 

Any ideas on how to fix this issue? Is it a Kontakt preference or a VE pro bug? Would upgrading to Kontakt 3 fix this issue? Has anyone successfully got Kontakt 2 to work in a VE Pro instance on their Daw machine in Logic? Like I said above, it works GREAT if I keep the record enabled button on, but once I take this off Kontakt will no longer play. Any advice would be greatly appreciated!

Funnily enough i wondered why this wasn't happening to people only yesterday. I don't use Logic, and probably don't understand fully how it is supposed t work, but my understanding is that when a track is record enabled, Logic plays back at whatever your soundcard is set at. However, when tracks are not record enabled it adds a buffer, so that it ignores your soundcard settings. Now my question would be, how does VE Pro "know" how much extra buffer to add during playback? Maybe there's some sort of setting in Logic?

When in playback mode, Logic uses the setting "Process buffer range" as plugin buffer size (Small = 512, Medium = 1024, Large = 2048). Once VE Pro is being sent a buffer of a different size - it will report back the proper latency to the host, and the host will start to compensate for the new latency. In the case of Logic, it will never tell the plugin about a new buffer size before actually sending it to the plugin, so a change between record / playback on a VE Pro track wil require one start/stop cycle before the new latency compensation value is used.

 Ah, thanks for clearing that up .

Any idea why Kontat does not playback previously recorded material in VE Pro unless I keep its track record enabled? I guess no one else has experienced this problem?

I made a quick movie demonstrating the problem here: http://www.fieldsfaraway.com/jon/VEprobug.mov

I also sent an email to VSL tech support. Hopefully between them and you wonderfully smart forum members we might be able to get to the bottom of this little issue! Thanks!!

The wonderfully knowledgeable "MS" Provided what seems to be the answer; the "process buffer range" in Logics Audio preferences. It seems Kontakt doesn't respond well when the setting is set to Large. I have since switched it to "medium" and so far so good! I'll be doing a full project here tonight, and will report back but its looking good so far!! THANKS Martin!

Just an idea, maybe you should add "solved" to the post title...
