What is the main difference between pitch-repeat2 and pitch-repeat3 functions? 

 

I'm testing various examples and notice that the first two parameters in pitch-repeat2 are low and high integers; in pitch-repeat3 there's only one parameter, count, which can be expressed as a single digit or a list. When the count is represented as a list, it produces a similar output of randomized high and low counts, similar to pitch-repeat2.

 

Any other comparison observations or differences between these two functions?  Thank you!

(pitch-repeat2 3 6 '(c4 d4 e4 f4))
=> ((c4 = = =) (d4 = =)
    (e4 = = = =) (f4 = = = = =))

 

(pitch-repeat3 3 '(c4 d4 e4 f4))
=> (f4 d4 c4)
