Preset manager causes interruption of audio

[Ariajazz]

Althoug Preset Manager is faster in Usine v5 it is causing an interruption of audio when recalling presets. In some cases it completely silences audio for a fraction of a second or with a click or pop noise and in other cases it just decreases the volume of the audio for that fraction of time. I have notice that it happens when the white trace display at the upper right corner appears, when it dissapears, audio recovers its normal level. I was trying to engage "silent edit" of preset manager present in previous versions of Usine, to see if it could solve the problem but it seems that this option is not existent any more in v5.

The most common issue is that Usine is not in charge of plugins presets. Usine just call the plugin function "save/recall" preset (it is inside the plug) and some of them are not really CPU friendly on this point...

Hi Senso, Thanks for replying. In my workspace configuration Preset Manager is not managing or dealing with plugin presets internally, i other words PM is not executing any preset change within plugins, it is only recalling "scenes" in the workspace such as switches, knobs and other control modules. This is because I'm aware that plugin's preset changes, as you correctly mentioned are not always fiendly and therefore I opted for a "saved in preset" option for the plugin deselected so the PM does not make any changes inside the plugin.

I feel this is not a plugin related issue. The behavior of the white info display box located at the upper right corner (used to be blue in previous versions of HH) gets my atention, the fact that the audio interruption and other artifacts are present exactly when and during this info box appareance makes me think that is has to do with the issue. I did a test of changing parameters within plugins by engaging them by using switches, buttons etc. and it just worked fine. When I tried to control these buttons and switches through preset manager the issue appeared. Again, the silent edit option of PM is not longer present in HH current version to confirm or dismiss things, It would be a good idea to have it back.

I don't think I've experienced this behavior in HH previous versions. Really have to go back and do some more testing. I really miss the old CONDUCTOR module from USINE 5 generation and former versions. It was absolutely efficient fast, noise and artifact free, and, by the way, it had bank-preset capabities. Why don't you guys just have it back in HH?. I've read from some people asking for it in this forum.

Anyone?

Are you using the new save to a file preset manager option ? When I tried that it caused some audio issues.
I found any time a disk access occurs on non-SSD drive it could have that effect - such as when one of my user modules
accessed a file.
Could you start with a preset on just one patch, then try a rack, then the whole workspace and see when the issues starts to occur.
Its also the case that if your PC is on the edge of running out of steam it doesn't take much to cause an sound interruption.
On my Dell laptop I had to stop all the Dell services else I got audio dropout on patch changes.

But I agree that just selecting a preset that only changes usine graphical items should not cause audio effects. Of course something a dial or
switch is connected to could result in a VST doing something CPU intensive.
I have always avoided whole workspace presets as I imagine it must load various system settings along with the switches, buttons, etc.

A general query about CPU and Usine. If the VSTs are running in a thread, can Usine restrict the CPU allocated to that thread so the VST
cannot hog the CPU ? (this might make the VST load slower).

Hi Simon, thanks for replying. I will take all you said in cosideration, will perform some more testing and let you know about the results. My PC is powerful enogh to perform fine with no artifacts due to CPU hog. The plugin used is Overloud TH-U which is the lowest CPU usage of his kind. The issue described is not present in previous versions of HH.
