Not the biggest fan of subscription models, but you can buy lifetime access. Workshop mentors need to make money, software developers need to make money so it's all understandable for a niche product like this one which is improving all the time.
Love the software, you can link accounts between steam and meta, use music streaming services like beatport (has to be advanced), and most importantly you get to use CDJs from the comfort of your home and share mixes with other DJs. The community is also great. If you are serious about being a DJ and don't have access to club gear or even if you want to try it out without buying your own controller I highly recommend this product.
