3D spatial mix visualizer · Logic Pro

TrackSpace

See your mix as a room. Every track becomes an object on a stage — left and right from your pan combined with what it hears, brightness measured and depth estimated from how it actually sounds.

If you can hear it, we can show it.

In development · a probe in Logic Pro and a separate Hub app

Probe + Hub app · macOS 11+

The TrackSpace Hub. A 3D stage seen from above and behind, with a listener marked at the near edge and axes labelled close, far, left, right, bright and dark. Coloured spheres carrying instrument icons sit out on the floor — a lead vocal, overheads, two collapsed groups — each trailing a thin line down to the surface. A sidebar lists the session's tracks and groups, and the header reports the Logic Pro control link as on with eleven channels matched. — Each sphere is a track: left to right is Logic Pro's pan combined with the measured balance, near to far is estimated from how the sound behaves, size is loudness. The two labelled Group are several channels collapsed into the one instrument you hear. Depth reads best on sounds with gaps — drums, percussion, plucked and picked instruments and most vocals; a sustained sound such as a pad is placed toward the back.

Your ears place every instrument in a room. TrackSpace draws that room.

A stereo file does not store where anything sits. Your brain works it out from a handful of clues in the sound itself — how loud a thing is, how bright, how much room you can hear around it. TrackSpace measures the same clues and puts the result on a stage.

It is a window into your mix, not a processor.

It listens to the result, not to your settings.

TrackSpace does not read your plugin parameters. A small pass-through plugin sits at the end of each channel and listens to what comes out, and the Hub draws the mix from that.

The practical difference: a reverb you left bypassed cannot fool it, because it is looking at the sound rather than at the knob. If a track sits closer than you expected, that is what the channel is actually producing.

What the stage is showing you.

On the stage	What it means
Left and right	Where the track is panned.
Near and far	How close the sound feels — dry and upfront, or back in the room.
Size	How loud it is.
Width	How wide the stereo image is; a mono source stays a point.
Height	How bright it is. This one is a drawing convention, not a physical height — brighter sounds are placed higher so you can tell them apart.

You can freeze the whole picture on one instant, leave a trace behind each track to watch where it travels through the song, hide channels that are not playing, and solo anything on the stage.

One setup step, and it is worth doing

Logic Pro applies the pan knob after the inserts, which means no plugin on the channel can hear it. So the Hub connects to Logic Pro the way a hardware control surface does, and reads the real pan positions directly. That setup step is the difference between tracks that follow your pan knob exactly and tracks that all sit in the middle.

You don't hear channels — you hear instruments.

A mic'd kit is a kick, a snare, two overheads, a room mic and a bus. A layered vocal is a lead, a double, two harmonies and a reverb return. You hear one drum kit and one voice; the stage shows you nine separate objects. Grouping collapses each set back into the single thing you actually hear — which is also the only way the reverb return counts towards where the voice sits.

The details.

Release status

TrackSpace is still in development. There is no build-it-yourself route and no buy button — it will be sold, with a signed installer, once it is finished, and not before.
