Mixed In Key

Hey guys, newbie to the forums here.

Started playing around 10 years ago, vinyl, belt driven tts, 2 chan mixer without a mid eq lol. Took a break around a year and a half ago, got back into it about 8 months ago. Went digital with Traktor and such and sorted out my music. I acquired MIK and tried it out. I thought it was pretty cool, my mixes sounded good as far as key clashing but felt like I wasnt utilizing my full library of music.

Started using my ears a bit more and just went with what Ive learned and it seems to be working out better for me. I find myself still looking at the keys but only if I wanted to do a new double drop or if it was a longer mix.

Thought I would share my thoughts but I was wondering if anyone else has had a different experience with it? After installing it, do any of you still swear by it? Anyone just felt like it was shit from the beginning?
