Basically what this feature would do is match the tagged bpm of deck A (deck you're bout to bring in the mix) with the tagged BPM of deck B (deck thats already playing). Before anyone calls me a cheater or microwave let me explain myself. What this feature would do is give you extra PITCH leaway (i dont know how to spell leaway lol) when you try to mix a slower song with a faster song. So if I want to mix in a track that is 92 bpm with a track that is 97 bpms I can start with my pitch at zero on the slower track and have room to breath when I'm riding the pitch in the mix. You would still have to make adjustments with the pitch because matching the bpms will not create a perfect mix so I dont think it's cheating or microwave. I can mix fine with this I just like the option of mixing from zero everytime. ALSO when you want to match up two records that are the same but one is at +4% this would make it easier to match them both up so you can switch between inst, main, and accapella more seamlessly since decks are never matched perfectly when it comes to pitch. I hope this makes sense, dont bury me :(
