the note repeat feature is update in 4.1 but there is still miss a 1/1 1 bar long note. so arp patterns that have mostly at least 1 bar are only play 2 times 1/2 pattern. so usefull is have a 1/1 setting and a 2/1 setting is usefull. I think this is not much work for you to program and can help alot. the note repeat enable is very usefull to have to trigger arps and not need press the key in perfect time.
