Crashes using melody imitaton

[Strings]

Hi, I'm having a lot of crash and strange errors using melody imitation (I'm singing melody into the mic but with earphones).
Here some examples, the feature is almost unusable, do you have some suggestion?

My os is win 10 pro

Thanks for any reply

Hello,

Do you get error messages? If yes, which ones exactly (add screenshots if possible).

Also, which build version of EarMaster are you using? To find out which build version you are using, go to the HEP menu and choose "About EarMaster".
