Patterning the number of steps in an arpeggio

[Git-Christopher]

The current iteration of arp functionality within function note allows you to specify the number of arpeggiated steps in a given chord; e.g. note (arp "updown" "c5'maj'**8**").

I would like to propose modifying the arp functionality to include a way to pattern the steps using mini notation; e.g. ( . . . "c5'maj'**<4 5 6>**") or (. . . "c5'maj'**[4|8|16]**").

Perhaps another way to approach this would be to add a third argument to arp; i.e. note (arp "updown" **"<4 5 6>**" "c5'maj").

Thank you for considering this feature!

would love for this to still become a feature!

With recent improvements to chord parsing, this seems to work now
