Hi, @pidukster,

That's called a Camelot Key - it's a method of assigning a unique code to every musical key, making it easier to mix your playlists and blend tracks seamlessly.

I'm not an expert on mixing by any means, but I think the main idea is that as long as you stay on the same number (8A to 8B) or move up or down one number (8A to 7A or 9A), you should generally get a good harmonic mix.

BPM also plays an important part in achieving this though, so it's worth paying attention to as well.

Hope this clears things up. Cheers 🤘
