It appears that it is not possible to access the parameters of the various FM operators in the arpeggiator destination menu. As soon as you move the mouse the menu closes without allowing you to choose. The problem occurs only for FM parameters. Same thing in the matrix section: the parameters of the FM operators are not reachable (only operator 8 can be set). Does it work for you?
I can’t reproduce the issue at the moment. The items in all dropdown menus of FM Lab are reachable and can be selected on my Win 11 system.
What operating system do you use? Have you already updated to HALion (Sonic) 7.1? Does the issue occur in the standalone version and in the VST3 plugin, or only in one of them?
Thanks Martin. My operating system is Windows 10, Halion version is 7.1. The problem occurs with the Standalone version although in the VST3 version there remains a bit of flickering when I select the operator parameters but it still works. Flicker is not there for any other parameters, only with operators.
Hm, that’s strange. Unfortunately, I have no idea what’s going on there and how to resolve the issue. Maybe you could check if there’s a more recent graphics driver available for your system. Probably someone from Steinberg needs to take a closer look.
Hi Fabio_T
I’m able to reproduce it here. Its now in our Defect-Tracking-System and listed as Bug-ID “HALLY-10902”.
I hope we can provide a fix for it soon.
Thanks for your report and please accept my apologies for any inconvenience caused.
