My logitech wireless mouse cursor froze in that CLAP version once. I switched from the receiver to bluetooth and back, and no problem since.Grizzellda wrote: Wed May 06, 2026 6:03 am Zebralette 3, CLAP version does not communicate mouse movements at all...but the VST3 version works.

MuLab Plugin M10.2.20 beta for Win64 is available:
https://www.mutools.com/mulab/plugin/la ... /beta.html
What's changed:
- Added support for resizing resizable VST3 editors using the host window borders.
- Due to a code change in M10.2.18 some older MuLab 8 projects could not be loaded anymore without upgrading using a previous MuLab 10. Fixed.
- Fixed a project/preset load error bug for files saved with M10.2.15 or up when it contains a Sample Player front panel item. (due to the extended wave color set)
- Making setup changes (eg. audio setup, insert user key, ...) upon the very first run was possibly not properly saved as the "Settings" subfolder did not yet exist. Fixed.
- Upgraded to the latest CLAP SDK 1.2.7.
- Further vectorized the GUI.
- Other small improvements.

Seems that the latest version, 10.2.20, at least on macOS 15.7.4, has broken the GUI scaling. It was working perfectly in version 10.1.25.

After a lot of trying, cause i didn't have a narrowed area where to test, i finally found how to repeat the issue. Will research & fix it.Bax9 wrote: Thu Apr 23, 2026 9:38 am I'll do all the tests, by now I can say you that every project or new project, WITHOUT INPUT MIDI so not playing keyboards but only playing back a song/arrangement, at certain point start to get crazy
some note disappears, some notes stucks open ...

I've researched this and talked to the Stepic dev about this and he has updated Stepic to resolve this issue. He told me that you can contact him to get a new Stepic beta version to test it. Thanks to DevicemeisterMuTools wrote: Sat May 02, 2026 9:15 pmThen it must be about a different issue.jd88 wrote: Tue Apr 28, 2026 2:33 pm "Fixed a serious timing issue on the output events coming from a VST3 plugin." <-
BUT: in the actual version 10.2.17 (MAC) it isn'nt fixed. (Tested with STEPIC-VST from Devicemeister). The same bug like I wrote you a long time ago. (delayed Midi-Output while MuLab is in recordmode)
I'll try to find the time to check it.

I had never solved before issues about lag between Mulab clock and transmitted midi/usb clock, now it seems more stable.
Can I suggest a smarter way, if necessary, to compensate this lag (knowed issue on whatever DAW) ?
something like a 'align midi/usb clock' where you can type (usually) a negative value to predelay the transmitted clock ?
Anyway, great job

anyway, everything is quite stable now, I think you solved most of the issuses with the last update !
keep up the good work

Yes small negative values are possible as long as its within the audio engine buffer latency.
Thanks for confirming MuLab 10.2.23 is quite stable now.

-I did have the audio engine crash a few times, specially when recording audio.
-If I save a project in beta it can't be opened in stable version.
-AppPreferences and LooksSetup was overwritten. So a heads up for people trying out the beta make a backup of the entire folder not just the exe and ID file.
-When changing color of track the rack scrollbar color is not refreshed.

I doublechecked audio recording, can't repeat a crash.Palunto wrote: Thu May 14, 2026 1:31 pm -I did have the audio engine crash a few times, specially when recording audio.
Please send me the MuLab log file of that crash you encountered.
It's in your MuLab/User/Log Files sub folder.
-If I save a project in beta it can't be opened in stable version.
Which error do you get?
If it happens again make sure to do MuLab menu -> Tools -> Keep Log and send me that log file.
These files are overwritten very often, that's normal.-AppPreferences and LooksSetup was overwritten.
Why do you expect them to be not overwritten?
Taken note, thx.When changing color of track the rack scrollbar color is not refreshed.
