I just got flstudio and I'm new to it, so I started creating music and I experienced very annoying thing. When I place a note in piano roll, or when I move a note from one place to another, a sound (that note) is being played. How to prevent it?

My english is bad, so if it is unclear what I'm talking about, here is screenshots. Here is when I [place a note](https://i.sstatic.net/lT2R2.gif) and here is when I [move a note](https://i.sstatic.net/Y7Qtx.gif). In both cases a sound is played (sound of the note). I don't want to hear a sond when I place or move note. I want sound only to be played when I click "Play" button. How to achieve it?

I searched on the whole internet and I spent more than a week searching in options and setting stc, but nowhere I found answer. Simply, I don't want to hear anything while I'm editing piano roll. I want only to hear song when I press play button, not while I'm editing. How to do that?

This is my temporary solution, which is very bad: I made a program in c++ which mutes all sounds in computer while I'm editing piano roll and when I finish editing piano roll, then I go to my c++ program, enable sounds and then play song. I am sure there is better way and I'm sure there must be an option in fl studio to achieve exactly what I want. I don't want to create external programs just in order to remove annoying sounds from fl studio. I want to do it natively.

So, if anything, absolutely anything, is unclear in my question (due to my bad english), then feel free to ask and I'l explain whatever is not clear. I tried my best to explain as brief as I could, I hope it is clear what I want and what I've tried and what the problem is.
