Unfortunately I’m having the same problem here.
Windows 10, 64bit with FMOD 1.10.11
I just tried the double click, the right click and everything but it looks like there’s no way to change the value in the tempo marker. Any suggestion?
Hmm. I’m testing using FMOD Studio version 1.10.11 on WIndows 10 64 bit, and double-clicking on tempo markers allows me to change their values without difficulty.
There must be some difference between my test machine and yours, but I’m not sure what. Are you running any accessibility software that might be altering the way your mouse button interactions are interpreted? Does the issue occur on other computers available to you, or just the one?
In FMOD Studio version 1.10.11 and earlier, there is no way to change the tempo of a tempo marker other than double-clicking on the marker or using a script to change the marker’s properties directly, so there is no easy workaround for the issue that I can suggest.
