Soften strings attack

I had a small piece of music on Maestro using ‘Slow Strings’.

I re-input it to Dorico and it sounds good except that the attack on the strings would be better if it were smoother.

Is there some way to achieve this, adding Legato didn’t seem to help much.

Can an envelope be applied to selected notes?

Regards, Rob.

The sounds on iPad are fairly basic, compared to those on the desktop versions – where of course you can use any of the countless instrument libraries that work through VST plug-ins.
