Are you running the original 04 release or the latest early access build? What is your thread scheduling model set to?

What version of cbb are you running? Can you share the project?

He's talking about the early access 2 release. It's not officially released yet. I'm not sure I follow. If you get a dropout there is always a toast message displayed telling you that.

Putting melodyne as a clip effect would certainly cause doubling of audio because its playing the clip audio as well as Melodyne. Its not intended to be used that way unless you like doubled audio

Its already in the early access 2 build.

This also has been addressed for the upcoming release.

I was referring to your export audio issue. Ilok issues would have to be addressed by the plugin manufacturer or ilok itself since that is out of our control.

This has been fixed for final release thanks to @Max Arwood assistance.

We've also contacted them but have not heard back yet.

@Billy Buck That stack was captured from the 04 release not 05. However the crash is in the plugin itself. There is nothing in the stack that shows the cause to be from Cakewalk. Please forward the dump file to the plugin vendor since only they can fix it. ------------------------------- Unhandled exception at 0x00007FFA1DE909A0 (BBC Symphony Orchestra (64 Bit).vst3) in Untitled_05262020_100755.dmp: 0xC0000005: Access violation reading location 0x0000000000000000.

I'm not sure why the GPU spike would affect Cakewalk's engine but one thing you can try is raise the value of DropoutMsec in the settings you listed above to something like 200-300. While that seems high it may get you past the fallout from the spike. You want to try and diagnose what is causing that however, esp if nothing much is happening in Cakewalk at the time.

Thats interesting. Do you see the same dropout even when not using Kontakt? It could be something interfering with Kontakt Cakewalk doesn't directly utilize the GPU so I wouldn't expect it to be affected but if a plugin depends on it its possible that it could trigger a dropout.

@Philip G Hunt please send me the dump for the crash and we'll look into it. The message shows the location of the dump file.

You can also add clip effects from the clip inspector on the left.

🙂 Of course MIDI was invented by Apple right?

So by extension if someone decided to arbitrarily name .wav file .wave we should support it right and it's a "bug"that we don't? 😕 Well verify if this is indeed coming from established Mac apps

MIDI only VST plugins are not supported. We may handle these in the future.

The MIDI specification doesn't list .midi as a valid extension. Standard MIDI Files ("SMF" or *.mid files) https://www.midi.org/articles-old/about-midi-part-4-midi-files

Where are you getting .midi files from? the standard extension is .mid not .midi. And CbB sees .mid files fine in the file open dialog if you pick "files of type MIDI"

@Skyline_UK you can't change science There are solutions to problems like this but the solution has to be implemented at the plugin level. Plugins are serial processors from the point of view of the DAW - i.e their buffers have to be processed in sequence so a single plugin must be processed serially. So other than introducing techniques that utilize larger buffers in the DAW there isn't anything further that can be done. The plugin needs to partition its work across different cores to have the most impact. Talk to the plug-in vendor and ask them to improve their CPU efficiency.

@Max ArwoodI'm glad its working well for you. Multiprocessing very system and load dependent and requires a lot of testing on different workloads so thanks for trying it out. If you can reproduce the problems you had with export please contact me and send a dump file since I was unable to reproduce the problem.

Ha then I bet they are not using the low latency size at all

Seeking to a different offset is not quite the same thing as actually trimming the vide because that is implemented at the video engine level and is reflected in video exports, looping, etc. Also you can relocate the trimmed video anywhere on the timeline and the thumbnails will show the correct video frames. If all we did was seek to a different frame this wouldn't happen automatically. Media foundation is rather complex - all the video playback is handled internally in the MF engine. The host sets up a video track with the clips and trim points and then all the playback is handled by the engine which we slave to our audio engine clock. The bug with trimming is Media foundation hangs whenever we set trim points. I had a lengthy thread with MS years ago and they were unable to figure it out at the time. I don't think they have many people who even know this stuff there! They seem to spend more time changing sdk's then actually fixing the stuff that has been broken forever. I'll follow up again and see how it goes

@Matthew Sorrels Very strange I can run it here with no issues at higher sizes. Tried 1024 and 512 with no issues. Does it happen with any project? May have to troubleshoot this on your system.

Can you please send me a dump file @Max Arwood
