By playing legato i mean holding the previous note while playing the next note?.Of course if i just play the next note without holding the previous one i get a retrigger.
Maybe we also have a different understanding of what playing legato style means but the behavior in Unison mode is for sure differnt from that in the polyphonic mode which indeed always retriggers each new note.
Example patches from my own factory presets are e.g. "Ultrasaw Lead IW" in the "Leads" folder and "Sizzle Lead IW" in the "Vintage" folder (which also contains some other Lead sounds from me).
