When you have several synths with an identical note region, you can gain some space in the timeline by using the notesplitter, instead of copy/pasting the notes in each synth. Can also be inputed into other notesplitters (when you have more than 3 synths to connect), or into the arp matrix. Pretty useful when using a midi keyboard, as all your connected devices will be triggered at the same time when pressing a key in the notesplitter :)
I also have a second piano patch in my drafts. A somewhat improved version but I still see points where it could be improved. Another point of view would be helpful, if you're interested I can invite you
