Feature "Once" :

[mr-eggleton]

Being able to designate a line or method to be only done once.

Problem, when you play something like this :

@nextBar
def a():
    d1 >> play("Xx")  #the drums we will solo 
    l1 >> pads() # the new melody coming in
d1.soloBars()

It sounds great but when you then add to l1 it runs it all again (including the soloBars which is never what i want).

Basically once() in should only run the code once unless it has been edited

Syntax suggestion 1:

@nextBar
def a():
    l1 >> pads() # the new melody coming in
@once
def b():
    d1 >> play("Xx").soloBars(end=True)

I don't like using a decorator for this but I'm not sure how to do Syntax suggestion 2:

l1 >> pads().nextBar()
d1 >> play("Xx").soloBars(end=True).once()
