This is the way my Tuesday therapy season usually begin .  Anyway, I'm having trouble freezing Vienna Ensemble Pro 5 in Sonar X2a.  My current project consists of 19 tracks inside VEP 5 spread across 19 midi channels.  Through Sonar I route the first 16 channels into VEP 5.  Channels 17-19 are routed into the same instance of VEP 5 using a VEP Event Input Synth.  So far everything sounds great, no problems.  When I go to freeze VEP 5, only the first 16 channels would freeze but the Event Input channels are lost.  That was my first problem.  I've posted this on VSL forums and haven't received a response so for.  So while I was awaiting a response I thought that I would download the demo of X3 and see if using the VST3 version of VEP 5 would help since X2a doesn't support VST3.  After doing that now I get nothing but silence after freezing VEP 5.  This is now my second problem.  Even if I freeze with "audio bounce" selected, I hear audio while it's bouncing, but not when I play it afterwards.  My frozen VEP 5 shows no audio data.  This is happening in the demo version of X3 and is now happening in my copy of X2a as well.  Thanks for any help you can provide to any of my problems (mental or technical).

I know that this is not what you are looking for, but I'm wondering if you can use Bounce to Tracks and get a bounced track of what you would have from the Frozen Synth. You could then just mute the Synth.

Try using real time bounce instead of fast bounce. You will see this with a right click on the freeze buttons in the synth rack. 

Thanks for the responses.  I did get a response from VSL and they said that they were able to reproduce the problem of not getting the channels past number 16 to not freeze.  They believe it's Cake's problem.  That I'm not sure about or am that concerned about.  I'm more concerned about not hearing any sound after from the first 16 channels after installing X3.  Before I installed X3 the problem was limited to channels 17-19 not freezing.  I was able to hear channels 1-16 after bouncing.  After installing X3 now none of channels freeze.  I get nothing but silence on the frozen track.  I've tried fast bounce and real time with no success.  This happens in X3 and X2.  This is really the main problem I want solved.  Any thoughts?   

x3 requires a reset and rescan of your plugins, whether this will affect your X2 install I have no idea, so be warned, maybe another user can chip in

Are you using the VST3 version? If you are, try using the VST2 version instead. When I upgraded to X3 I tried to use the VST3 version resulting in silent bounces. Switching back to VST2 was the temporary fix. Might want to Save that setup within VEP before switching then load vst 2 version, then open VEP save.
