Weird sound in VST strings

I found weird sounds in virtually all kinds of VST strings, no matter from the HAlion sonic SE or the HALion Symphonic Orchestra.

The sounds only show up for particular notes like B3 and E4 and which varies with the type of string. It sounds like a mixture of flute and diminished strings. I am sure that I didn’t do any mixing or modification on its original sound.

What’s going on?


Could you share the name of the exact sound preset, please? And could you write, which Volume of the Note are you using? There could be more layers for different volumes.

The sound sample would be also helpful to investigate.
