In the Song Editor I can't open the piano roll

[Miki]

Hi everyone, I was working on a project when they no longer managed to enter the "piano roll" of any instrument in the section: Song Editor.
Thanks in advance and I hope there is a solution

I am almost sure your piano-roll is opened fine, bur it is outside your view!
Close down song-editor, then scroll as far as you need the right, i think you will find piano-roll there.
If you do not
please post your:
* Name of your Operative System (Windows/ Linux/ Mac) And subtype ('Home' 'Mint' '10.13' aso)
* lmms version

i will btw remove your italian version of this question, since its not needed :)
