Unfortunately, I’ve been unable to reproduce the issue on my end - when using the programmer sound example code, I’m able to call FMODUnity.RuntimeManager.PauseAllEvents(true); to pause all events, including those that are currently playing programming instruments.
Are the details (i.e. FMOD version, Unity version, etc.) in your previous post about programmer sounds still accurate? If not, could I get you to provide the version numbers that you’re currently using?
