I’ve had this problem for a long time, just wanted to post and see if anyone else has this issue. I don’t have exact repro steps yet, just want get a feel if anyone else reproduces anything like this.
When I save a session in Nuendo with UAD plugins inserted on a track but powered off via insert button, reopen the session at a later date, enable (power on) the previously disabled UAD plugin, the plugin always fails to process audio (dry audio passes). The only way to fix it is to drag the insert to another track and back or toggle the mono/stereo menu in the top right of the plugin header bar (dragging to another insert on the same track will not fix the issue). I have not experienced this with non-UAD plugins.
UPDATE
My System:
MacPro 1,1
RME Fireface 800 x2
Nuendo 5.5
UAD 6.0: 3x UAD quads
UAD meter app settings: DSP limit 100, DSP load lock ON, extra buffer OFF, release all DSP for AU ON, force logic OFF, controls mode linear
create new empty session (44/24)
add 4 stereo audio tracks
insert a steinberg test generator plugin set to white noise into insert 1 on track 1
in the mixer, drag + copy this test gen plugin to each insert #1 of the other three tracks (2,3,4)
insert a UAD 1176 on insert 2 of track 1
—note the 1176 is processing, the VU meter is activate
power off this 1176 plugin on track 1
drag copy track 1’s powered off 1176 plugin to track 2 insert2
drag copy track 2’s powered off 1176 plugin to track 3 insert2
drag copy track 3’s powered off 1176 plugin to track 4 insert2
as all test gens on all tracks are producing audio, power on track 2’s 1176 and watch its VU meter
—no meter activity is seen
repeat step 10 for track 3
—no meter activity is seen
repeat for remaining tracks
I am able to repeatedly perform this test with these same results.
Am I right in thinking this happens if I load a project with UAD plugs switched off, or with them bypassed in Nuendo, but if i switch them in, save the project and re-open, they will be working? I’ll try this later, I generally just re-open the plugin.
I wonder why some UAD plugs do it and other UAD plugs don’t seem to?
Have you filed this with UA yet?
If not, then it might be a good idea to do so - and tell them also that you can get a load more names of people with this problem too. I’ll look around, but I am sure I seem to remember it used to happen on a couple of other makers too, but they fixed their bugs where UA have not.
Neil,
Did you read through this thread? One other person including myself have been told by UA that the issue was not on their side. As I also said earlier, I have not experienced this issue with any other plugins.
Furthermore, having been using Nuendo since version 1.0 we (myself and several other users also in this thread) have been living with this issue since version 4.0.
There is no question this is an issue given other people’s reports. Given the nature of the issue, unless I find another plugin that also has the issue, I cannot proove for sure where the issue lies.
Rather the speculate, I’d like a response from Steinberg on the issue.
I have never had this issue ever before with other plugins besides UAD. Yeah, I know this seems to point to universal audio, but they told me the problem is with Cubase and Nuendo.
This kind of reminds me of the broken PDC that was presumed to be localized solely UAudio plugins, but as it turns out it was not, coming at the expense of the user base’s time to find plugins outside of UAD plugs that broke the PDC.
It would be nice if Steinberg could take a peek at this. I do believe the OP should re-post the 1st post in this thread with a repro of the issue so we can conform to Steinberg’s bug reporting standard.
I have scene the following behavior several times over the past couple of years using UAD plugins. Essentially I am occasionally seeing plugins that were saved in the OFF state (no DSP processing) not processing audio after session is loaded and plug in powered on.
add a bunch of UAD plugs to tracks in Nuendo
turn them off, no DSP running
save the session
close/reopen Nuendo
load same session
enable said UAD plugins
plugins will pass DRY unprocessed audio
Work around:
Drag the plugin to a new insert on a different track or toggle mono / stereo menu on plugin header.
I retried these same steps in Nuendo 5.1.1 on OSX 10.6.8 just now and was not able to repro, however I often experience this issue at least once or twice a day while working.
That said, these aren’t exact repro that always produce the issue, but as we all know that doesn’t mean a bug doesn’t exist. I’m happy to see others are too experiencing this too. I will gladly post exact repro if I am able to discover them.
