Dorico 6 Pro Export Audio Briefly Cuts

I am using the most recent version of Dorico on Windows 11. The VSTs I’m using are Spitfire SO, Spitfire Epic Choir, BBCSO and Band (a free VST in Kontakt). Alto Flute uses Spitfire SO, Bass one and two use Epic Choir, electric guitar uses Band and the rest are BBCSO. I am also running all instruments through RoomWorks SE, with the exception of Bass Ahh (choir bass) which uses REVerence. The output is running through the built-in Steinberg compressor. I have modified a few of the plugin settings, but nothing major - everything is, essentially, default configurations.

Exported MP3 and WAV files have a one second dead silence in the first 4-6 seconds (different places for each filetype). I have tried disabling the ASIO guard, increasing the pre-roll, changing max voice and preload sizes, modifying the particular measures where it happens changing plugins, nothing has worked. My primary assumption is my CPU - I am writing on a miniPC, but if I export with a repeat at the end, the repeated beginning will not have a blank spot. Does anyone know what is causing this? I would both hate and love it to be a simple fix.

Not always dead silence, sometime only a very brief glitch where only one voice can be heard (typically the vocals). This seems to only be the case when ASIO guard is disabled.

Hi @Kristopher_Thornton , have you tried other ASIO drivers such as ASIO4All or FlexASIO. Or do you maybe happen to have still the old Generic Low Latency ASIO driver from Steinberg around. Because with that one you can still change the buffersize, something that you can’t specify in the new Steinberg Built-in driver, but it’s on the list of Todo’s.

If all tjat does not work out we need to take a performance recording on your PC, but let’s first do the first step and if that does not help, we’ll do the next, okay?

Thanks for your understanding

I have tried Generic Low Latency ASIO, ASIO4All (with as large a buffer as possible) and FlexASIO and both have the same issue. This is the computer I am using - https://www.amazon.com/dp/B0DPMLG4FY?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1

Okay, thanks for trying. Then we need to take a performance recording during export on your machine. First please check if you have Windows Performance Recorder already installed. Therefore please that term in the Search field on your task bar next to the Windows icon. If you don’t, you need to download the Windows ADK from here.

Once installed, launch the Windows Performance Recorder, prepare Dorico for an export but don’t invoke, yet. Then click the Start button in the Recorder and immediately trigger an export in Dorico. After 10 seconds stop the Recorder and save the output to a file. Please zip up that output file and send to u dot stoermer at steinberg dot de.

In case of question or doubt please don’t hesitate to ask.

Thanks

I have sent the WPR recording

One other thing - I had been using the trial of Neoverb, however, I uninstalled it after the trial ended and changed everything in Dorico to RoomWorks or REVerence. In demo mode, Neoverb outputs blank spots in the audio.

According to NeoVerb, “In Demo mode, the plug-in’s output will insert silence at regular intervals.”

Are you sure you have removed all of it? Have you restarted your computer?

Thanks @Kristopher_Thornton , I received your data.

I will hand it over to my specialist for analysis. She probably won’t be able to immediately jump on it, so a little patience please. Thanks

@jaskarbong Yes, several days ago. Completely uninstalled, had to re-rack two instruments and changed all plug-in’s to Steinberg plugins

And which exact version of Dorico are you using, @Kristopher_Thornton ?

I mean the version number.
