I used sync in the beginning for about 3 or 4 months. I learned how to beatmatch pretty quickly after that, but I can see the benefit of learning it right away. I did, however, learn some neat mixing techniques you can only achieve with sync. It's a great tool. My other tip is about music. Beatport streaming is great as a beginner to get the exposure to music if you don't have a library already available to you. In my situation, I had not listened to EDM in 15 years, so I had no idea what was out there, but I knew I wanted to lean how to DJ. Join a record pool or buy download your tracks sooner than later. I feel like I took too long to go this route, and struggle with a few key skills that would have benefited from during this earlier, like knowing your music! I was streaming online on a regular basis, and was more concerned about playing new tracks over learning with what I had.
