Camelot DJ is a Chrome extension developed by raquel.io. It is a free add-on tool designed specifically for DJs who use Beatport. The extension enhances the functionality of Beatport track lists by adding a column that displays the BPM and key in Camelot notation.

With Camelot DJ, DJs can easily filter track lists based on their desired key. Whether it's your Main Cart, Hold Bin, or any Top 100 list, the extension allows you to quickly identify tracks that mix well together.

In addition to the key filtering feature, Camelot DJ also includes a dashboard where you can select a specific key. Once selected, the extension automatically filters the track list to display only the tracks that mix harmonically with the chosen key.

It's important to note that Camelot DJ is currently in beta, so there may be some quirks or issues that you may encounter. The developer, raquel.io, encourages users to provide feedback to help improve the extension.
