Hi Paul. Yes, thanks for the quick reply. I'm using VE2, build 3711 as a plugin in Logic 8.0.2 in OS 10.5.7 on a Mac Pro. I have other computers in my setup but only run Vienna on my main Mac. I run VE2 (2 instances usually) as a multi-output instrument in Logic. So I've set up a bus within VE2 to go to a Logic aux chanel that feeds to a reverb. That way I can use VE's sends to set the amount of reverb on each instrument. I only noticed the problem happening after I updated to Logic 8 and OS 10.5 a few months ago. Before that I was using VE2 in the same way and having no problems with this setup.
So as it is now, I have maybe 5 instruments opened in an instance of VE2. I create a bus in the plugin and set it's output to HW 3-4. Once I am playing back at least 2 instruments at once, the popping starts. It almost sounds like a clocking issue, but it's coming from within the plug-in. The popping is coming only from the bus channel and it doesn't matter what HW output I set for the bus, still popping on that output. And if I set up other busses and route the instrument sends to one of those other busses, then the popping happens there. And even if I set the sends to go directly to HW 3-4 without going through a bus, the popping still happens at that output. And just to be clear, there's no popping unless 2 or more of the instruments are playing. You know, I don't know if this might have anything to do with it, but I'm running my Logic sessions at 48k, not 44.1. Could there be some clocking issue within the programming of the sends in the plugin?
By the way, if I run each VE instrument to its own HW output, so each has it's own aux channel in Logic, and I set the effect level on each Logic channel individually, then everything works fine. This is my temporary work-around, but it means I can't use the sends from within VE2, and I guess for other people it means they can't use the convolution reverb?
Anyway, thanks for the help. Please ask us if you have any more questions about our setups.
