I would like to combine a list of several chord sequences into a single chord sequence. So far, I suspected this would work but I get the error below. Any help would be appreciated!
Hi brandonc!
You’re right, #'merger expects 2 sequences as input (it should possibly include a method where one argument is 'nil, just passing the other input through).
In your case you can either #'reduce the #'merger function across the list of chord-seqs, or, if you prefer using omloop, take care to pass the first element (car) of the input list as the second argument to the 'accum-box, and iterate over the rest of the input list (cdr):

2 methods to allow #'merger to handle empty arguments:
(defmethod merger ((self1 score-element) self2)
self1)
(defmethod merger (self1 (self2 score-element))
self2)
I’ll test these a bit more, and if Karim approves, add them into the code.
