UI Periodically freezes for around 5 seconds then resumes.

[coalvilledave]

Hydrogen version * : 1.0.2 Operating system + version : Windows 10 Pro N, 10.0.19043 build 19043 Audio driver + version : Realtek onboard sound card

---

This issue also happens on my HP laptop which also has Windows 10 installed. The UI hangs periodically (roughly every couple of minutes), which sometimes shows the "Not Responding" message. If I'm playing a drum song, the timeline stops and I'm unable to click anything but the song continues to play and the app is operating fully as far as I can see.

When the ui resumes, any buttons I clicked are actioned and the timeline etc continues normally.

• H2 version : see 'Info - About', or in case you build Hydrogen from source use 'git rev-parse HEAD' ** if you are reporting a bug, please describe how the bug can be reproduced

[cme]

Interesting. Can you enable debug logging (Debug -> Log level -> Debug from the main menu) and then open the debug log shortly after one of these hangs? (Debug -> Open Log File)

[coalvilledave]

Thanks for replying but the main menu only has "show audio engine info" under the Debug menu item?

[cme]

Sorry, I forgot how recently those menu options were added, I thought they'd been around longer, they're not in 1.0.2.

Instead, start Hydrogen with logging using:

"c:\Program Files\Hydrogen\hydrogen.exe" -V Debug

[coalvilledave]

I've done this, but where are the log files saved?

[coalvilledave]

Here's the log output - it froze once about 20 seconds in to the track I was playing:

May I should just download the 1.1.0 beta release?

[cme]

Hi! Sorry, I didn't get round to checking here until now. Piping the output to a file with ....\hydrogen.exe -V Debug > output.txt is almost certainly the most convenient way to get the output.

But, yes please, do try 1.1 beta! It would be good to discover if there's an issue that affects it before actually releasing 1.1. Thank you!

[coalvilledave]

Hi, I've tried 32 bit version and the new beta and this issue occurs on both.

[cme]

Hmm, that's unfortunate. If you have 1.1.0-beta1, could you get the complete debug log using the menus, and post here, please?

Also, which audio system are you using, PortAudio, or JACK?

I've been unable to replicate anything like this using my windows vm.

[cme]

Also, is this demonstrable with just one particular song, or can it be any song?

Thanks!

[cme]

I notice that the song you're working with is stored on Z:. Is this a network share that takes time to access? Hydrogen will auto-save the song if there have been any modifications every couple of minutes. If it takes any noticable amount of time to save to your network server, this might be the cause of the issue. You could confirm this by checking for the presence of *.autosave.h2song and seeing if the modification times line up with when you experienced the pause.

[coalvilledave]

Hi,

Bingo! when I move the song file to my desktop the issue doesn't occur (although watching the time arrow I can see a tiny pause every 20 seconds or so, presumably when it reading from the now local file). I'll copy the files onto my laptop's local drive for now. You may want to ticket this issue for fixing at some later date though. Many thanks for your help. I've been using the software to record drum and guitar tracks that our bass player can use to rehearse to and it's been spot on apart from this minor issue.

[coalvilledave]

Btw if you could point me to a donation link I would be happy to donate towards this project.

[cme]

Bingo! when I move the song file to my desktop the issue doesn't occur (although watching the time arrow I can see a tiny pause every 20 seconds or so, presumably when it reading from the now local file).

Excellent! How large is the the .h2song file, in this case? It's surprising that it takes 5 seconds for the network activity but I guess that depends on a lot of factors, and Windows is probably holding the thread up until it's flushed.

It would probably be better to do the auto save as a background worker process, I think that should be viable with only a small amount of code change :)

[coalvilledave]

The file is 143k. I'd give you a hand but I'm a C# developer by trade. Good work with this though.
