Performance issues on FL Studio 20.7.2 (Windows)

There's a bug that makes threaded midiOut calls not to work, throwing TypeError: Device is not assigned each time a midiOut call is done this way.

This is being investigated by Image-Line.

It seems the bug happpens from time to time and there's no way to predict if the bug will happen or when. However, it might be due to an error on the initialization of the script by FL Studio's Python interpreter.

The constant error cascade that gets printed on the Script output also causes a performance drawback until the script gets reloaded and no error happens.

At the moment, Image-Line has not been able to reproduce the bug on their side so there's no fix for this yet.

The only workaround for this is to reload the script if you notice any kind of performance issue. Go to View > Script output > "the tab with the DAW device name on it" and click on the Reload script button until the cascade stops and no errors seem to happen.

On FL Studio 20.8 Beta 1 (Windows build 20.7.99.1961) the error doesn't seem to happen anymore.

This issue seems not to happen anymore on FL Studio 20.7.3 (build 1987).
