Change note length without deleting following notes

hello there again,

is there a quick hot key, or command so i can change 16th notes to 8th without deleting every second?

thank you

Turn on Insert mode by pressing I.

press Q for activate the chord mode, then the note you go to change length don’t delete the next note

Yeah that works perfect!

yeah this works too, but then the notes overlap each other, but it works too ^^

If you don’t want delete the following note I think that the overlapping is normal.
Maybe you need to reduce the rhythmic grid? I’m supposing too that you need to apply more length to your note but not too much to overlapping the following note. In that case you can reduce the value in the rhythmic grid that we have at the bottom left.
