Uncle Studio reads the tempo, the key and the beat grid of every record you give it, plans the transitions on the phrase, and prints an hour you would actually play. Then it hands you the timeline so you can argue with it.

The whole argument happens at the seam.

Anything can crossfade. The difference between a mix and a playlist is what happens in the eight bars where two records are both playing.

Phrase

It counts in eights

Transitions land on the phrase boundary the way a person would count them in, not wherever the fade happened to reach zero.

Bass

One bassline, always

The outgoing low end is gone before the incoming one arrives. Two basslines at once is the sound of a mix going wrong, and it never happens here.

Key

Moves that resolve

Every record gets a key, and the next one is chosen from what actually sits next to it — same key, a fifth away, or the relative minor.

Take the record apart.

Four stems per track, separated on the graphics card. Drop the vocal out of the outgoing record, ride the incoming drums underneath it, or pull a loop you like and keep it. The separation is a menu item, not a project.

And when the record you need does not exist, it makes one.

A generator lives in the app, installed with one button and running entirely on your machine. Ask for the eight bars of drums you need to get into the next record. Two to four come back. Nothing reaches the timeline until you have heard it and chosen it.

Give it a folder tonight.

If the second transition is wrong you will know within a bar — and you can fix it in about that long.
