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 point to the exact sound (preset), the Key and the Velocity, please?

Could you attach the sample, please?
