TOPIC: How to do legato?

I want to link notes without their attack sounding. It's possible? I have created a soundfont and exported it to musescore. If the notes are articulated it works well, however legato, slurs, trills,... do not work because it articulates the notes

that is a Musescore problem, they use the worst synthesizer available in the world in an attempt to protect their MuseSounds.

Thanks bottrop.
I can't find any information about it. I know there are many entries and maybe what I asked is already there, but the forum search engine doesn't work for me.
From a note I created a soundfont. I have expanded the range and looped it for the duration of the note. I don't know how programming modulators works and if I should do it from there. The idea is to do legato without providing another audio sample. It's possible?

PD: I don't speak English. Sorry for my English

in the Instrument view you set
Vol env Attack something between 0,080 and 1 second for your sample
Vol env Release 1 to 2 seconds
just try till it is to your taste
