Thanks!
The challenge actually made the track a little easier than usual because the mixing/mastering phase wasn't as stressful as it usually is, haha. Most of my songs have a lot of layering going on and a lot of sounds, and during the mixing/mastering phasing, things can get muddled and I have to be careful, and it can be annoying haha. Sometimes, I have to restart.
Most tracks of mine have roughly 20-30 different audio channels.
And, yeah . . . I've really gotten into dabbling in tempo automation, haha.
