Pal of mines been teaching me harmonic mixing. One thing i tried was searching in serato for 4B and it showed all the 4B tunes that mixed in key had named for him. I then randomly worked my way through the list, majority of tunes i had never listened to before let alone mixed. Will post TL soon. Ive also taken on board advice given on my video mix "stop touching the platter", so hopefully you'll see the difference. Cheers .
