Pro
Pro mode
The same song, with the rest of the tools one tap away.
Simple and Pro are a switch at the top of the mix. They share one project. A change in either place is the same document, and a connected tool sees that document too.
Simple keeps the finish button, the four sliders, the split, and the styles. Pro adds the tool wall: tempo, key, pitch, groups, loops, loudness chips, and a way to record one part. Make it sound finished is still the first button there.
Pro also shows mute, solo, and pan on each track, a marker you can drop at the playhead, and a send that puts the first track in a room. The master ceiling and the loudness target are printed at the top of that column.
Stay in Simple until a slider is not enough. Pro is the same song with more handles, not a different app.
