I'm selling a Pioneer SR controller. I bought it approximately 8 years ago. In the last 4 years, I've only turned it on about 5 times. I understand that I don't plan on using it in my daily life, so it's just sitting on the shelf collecting dust. Regarding its condition, I used it previously with Traktor Pro, customized the necessary mapping, and everything worked fine. I haven't personally used it with Serato, but a friend who recently borrowed it from me said that everything works perfectly and there are no issues. I can't say much more, but as far as the DJ controller goes, everything is okay, and I haven't encountered any technical problems.
