MIDI Editor trouble

Hello!

Today I faced a problem in Cubase Elements 10.5.20.
I can write only quarter notes in MIDI Editor.
See screenshot below.
Maybe, wrong some settings?

Can anybody help me?

“Length Quantize”

Ok, but I can’t find this option to change.

Then you certainly haven´t looked very well… You can easily find it in the manual.https://steinberg.help/

You’re right! This option was hidden)) Thank you!
