Hi there,
I had an identical issue to the one in the video posted by 'jaumepardalito' . The curious thing is that I have two slave computers.... I setup the first slave with 1 VEP instance with 6 x Kontakt 5 Plugins running 16 channels. I used the event input plugin in Logic to create the 6 MIDI sends to VEP, these had I/O utility plugins inserted, sent to 1-2 and then bypassed. To return audio to logic I used the main VEP 2x16 stereo multi-out plugin, with the '+' button hit 5 times to give 6 stereo inputs from VEP in total. I DID NOT have I/O utility plugins bypassed on the additional AUX returnn channels, but I did have one inserted on the MAIN VEP 2x16 stereo multi-out plugin.
Everything worked fine. I was able to record and playback material no problem at all.
I then duplicated this setup identically to the second slave systems. When not in playback or record everything worked fine. When playing back or recording the ISSUSE arose - not all notes were getting through to VE (MIDI registered in Logic), there were MIDI drop-outs and sometimes I got NO SOUND AT ALL. Very frusrating.
I will try adding bypassed I/O plugins to every Vienna plugin in the UNIVERSE. See if that fixes it. If it doesnt this is a major issue as its a super important studio setup I'm working on.
Any help at all appreciated VIENNA!!!
Thanks,
CB.
