Dropouts in 2.7.13

Hi Rory, something happened in the latest build 2.7.13 (Aug. 3), causing bad glitches and dropouts in Ableton. These were not there when I exported vst from previous beta. Importantly, dropouts happen when using sliders.

I was using my instrument that I sent you here: New openGL() mode identifier

I didn’t notice any dropouts, but if they must be caused by the changes made to fix the automation problems. I’ll take a look.

I think the difference appeared between the last beta and the one after automation fix, but I’m not sure. Try wiggling sliders - only then I get dropouts.

Sorry! It seems you’re right, it was before the automation fix.

I just tested here and I couldn’t get any dropouts? Check the video, and apologies in advance for what I’m doing, i’ve no idea how to actually use this plugin, I’m simply twisting sliders :rofl:

I will try the latest public beta a little later today, but after a good few minutes mucking around with it I can’t get any dropouts. Perhaps you’re using it with other plugins?

Strange. I have no other plugins but a rather low buffer of 128 - maybe this could invoke it for you?

… or maybe you used an even fresher Cabbage to cook this up :slight_smile: I’ll probably be able to get back to cooking in the evening.

I just now tested with the last available build in Azure and I didn’t notice any dropouts when I tried the same thing, only this time with buffer size set to 128. Let me know if it works when you try it later. I’ve pushed the changes for cabbageChanged this morning too, so you can test them also.

I tried it with the latest beta now - dropouts still there :fearful:
I also tried a random example (Bassline_TB-303) and I’m getting dropouts there as well. So it seems it is not my instrument, and since the older beta did not cause dropouts, it must be something related to the Ableton fix. I’m using Ableton v9. Could it be related to that? I hope there is something you can spot.

I’m going to fire up Live 9 here and see if I can get the same issues…

[edit] no issue here with Live 9 either. Did you revert to an earlier beta, export and try again just to make sure?

Great that you could test it! But strange with my system. I had the older vst already exported before and now I tried again reverting to 2.7.13 from July 30 - back to no dropouts.

My system is MacBook Pro (Retina, 15-inch, Mid 2015) with macOS 10.14.6.

… and there is also the thing with init of the S/L (Save/Load) buttons in my plugin. The preset gets loaded at init with the later beta. I can prevent that but something else is different between the two betas other then the obvious upgrades that you did.

I’ll trigger a new build with the live specific changes removed for you to try. At least it will rule that out or not. My Mac is 2013, high Sierra. Have to put the kids to bed first though :stuck_out_tongue_winking_eye:

Btw, it all works fine in other hosts?

Thanks! I’ll try in Garage band - the only other DAW I have available at the moment. Btw. if the vst file name has a dot in it, I get this tiny GUI - I think you told me that it has to do with parsing the file extension

I just made an AU and no dropouts there - in Ableton! Also no issues in GB. I have only tested with VST. Have you tried VST?
I had problems with AU in the past related to automation, so I kind of dismissed it, but I might find other issues with AU now :wink:

I’ve only been testing with vst 2.4. do you have Reaper installed?

New pests:
(1) AU doesn’t seem to broadcast internal chnset - a ghost from the past.
(2) AU has the same problem with recording automation as you fixed for VST - you have only one shot to record it, the next time around it doesn’t do it anymore.

These issues are soooo frustrating making plugins unusable as plugins.

I have no other DAWs to test with at the moment. I could install Reaper perhaps…

Are you running these AU tests with Live or GB?

Your plugin works without any issues for me, as the screen-grab showed. So, your plugin is completely and utterly 100% usable as a plugin here, with automation in both Live 9 and Live 10. I hope we get to the route of what’s causing the issues on your machine.

No dropouts in Reaper. I never used Reaper, so I’ll get a test run on it these coming days. Great news that it works on your system. Thanks for testing! It seems I might need to do some upgrading - which really annoys me. But I don’t know if there are any other options?

Automation recording test in Live.
