Hi mw design,
I got good results with:
in the tab Advanced (right upper corner) in Vienna Instruments Pro and then the Advanced tab (in the row "Mixer, Voice, Edit, Stretch, Advanced") at the right side of the window a little lower.
In this tab you can set the Start Offset to 50 ms at most, in this way you cut the first 50 ms of the sample (less is also possible of course). You have to adapt the Start Offset Attack also a little to avoid a click at the start of each sample (about 15 ms?... just listen what sounds well). With Legato patches you get a more legato sound in this way. Of course this settings only work on the selected cell in the midst of the window. I hope this helps you.
