Learn the trade on your 800’s. It will make everything very simple later, whichever new gear you choose. When I used CD’s. I wrote down all the info under the track name. Ins, outs, drops, breaks, endings etc. In most house productions, those bars, translates in to time when you use CD.
In the tempo around 125 BPM, it’s like 15 sec, 30 sec, 60 sec. If there’s a 30 sec intro, it’s a good chance the track is divided into parts of 30 sec’s. After playing around for a while you’ll recognize this, and knowing a break/drop coming a at certain time, just match you intro against that time. Using time instead of bars means you don’t have to count… 🙂 .
