If you have to ask, it's cheating. Ha ha. Of course it is. You didn't play it. And neither did anybody else. And that's that. No amount of rationalization will change it. Did you give the ARP credit for its performance?
I've cheated quite extensively in the past when I was struggling to be able to play. Lots and lots of strategic punch ins and outs. Then I'd do these logical contortion exercises..."this isn't cheating or anything, no, not at all...the computer isn't even recording my whole guitar anyway...just samples of moments of time..yeah...it's not really real anyway...my computer is generating the sound...ooh good one...all sound is computer generated at the end of the day, ya know? nothing to see here.."
I never worried about cheating on my homework in high school and I won't lose a lot of sleep cheating on my little songs that next to no one will ever hear.
