I love that it’s currently possible to place down a single note and have it perform fantastic arpeggio effects, but it’s impossible to see those at a glance when looking at the screen. 

Could we have alternate appearance notes for the generated patterns? 

Perhaps a similar technique could also be useful to show the length of longer instruments  like pads. 

Yes it's a good idea. For the length of longer instruments, if I add some control over note length, it will be fixed 😁

That's excellent. Thanks!
