Well basically, if you think of deodorant....Speed Stick, for example. The full name of it is Speed Stick by Mennen. Come on admit it...you just heard the jingle in your head...
But do you ever actually call it Speed Stick By Mennen? Probably not. You call it Speed Stick.
As such, I will just call this Cakewalk. Yes, I know it's by Bandlab. And if they had a cool jingle to go with it, I'd probably sing that as well, however, I would likely only call it Cakewalk in every day speech.
So if you must shorten it, CW works just fine. Or even Cake. Or Sally. Whatever you want. Not sure why it matters.
Which reminds me, I need to go to the store and buy some more Speed Stick. I'm almost out.
