BUILT IN PSYCHEDELIC UNIVERSE LABS

「 I'm the guy behind one of the largest Psytrance channels on YouTube. I built this tool for myself. 」

After years of mixing I started asking: how can I simplify this process? Organizing a playlist by harmonic key is tedious — it can eat up an hour before you even play a single track. So I built something that transforms your playlist into a perfectly sequenced tracklist automatically, in seconds. After testing it on my own sets and seeing it work, I decided to share it with the community.
