I’ve experienced this same problem…but I thought maybe it’s supposed to be that way. Because the special “legato” of Iconica works by taking a single note you’re playing and making as smooth a transition as possible to the next note you play. If you were playing multiple notes at once, maybe it wouldn’t know which note to connect to the next one? So it can only do one at a time…? This is just an idea I had. Still it’s kind of lame…
