[Mac] Why does the synthesizer plugin automatically silence?

[Kirby47]

Hello everyone.


I am using the Ableton Live 11 Suite on M2 Max MacBook.

I found that inserting a synthesizer plugin on the midi track and running it for a period of time occasionally encounters issues with silence. It will no longer continue playing sound during any operation. And there is no signal on the level meter of the track.

At present, I have found that two synthesizers will encounter situations like this, Spire and Usynth, they are all AU, authorized, and the latest version.

How did this strange problem arise? Or how can I solve it?

Maybe you’re accidentally changing the volume or filter on them with a midi controller?

I have never performed such an operation. It fell silent after a period of time. Of course, such things don't always happen. Spire occasionally appears when changing presets, and then there is no sound, so it can only be resolved by reinserting the plugin.

Of course, they are all AU. I haven't encountered this issue yet when using their VST3 version. But I am still confused.

Could be a bug with those synths.
Did you contact Support and/or the synths developpers?
