Logic Pro X is playing wrong note(pitch) from visual piano rolls.

Hi

This is Jungwoo.

I have been facing issues of logic plays wrong audio pitches in different VSTS.

For example, when I play 'C' it shows that C is playin in piano roll but plays 'A#' in audio.

I tried logic virtual keyboard and midi keyboard and it has same issues.

I call logic technical support and they told me to check plugin components and I tried every single one and it still does same thing.

It sometimes plays right note but than it suddenly plays wrong pitch.

I think there is some bug between midi note and audio conversion.

I'm using Catalina 10.15.6 and I'm using Late 2015 Macbook Pro 15" Latina.

If anyone had same issue, please help me out.

Thank you.
