The Live Visualizer
Every preset's page has a Live Visualizer: a real-time mirror of every connected device, one panel per slot. Sticks, triggers, buttons, keys, touch points, and MIDI knobs light up as they move. It answers two questions constantly: is the Mac seeing this control, and what is it bound to.

Layouts
Each slot can show a controller, a keyboard, a touchpad, a mouse, or a MIDI instrument, and Auto-detect picks the one that matches the slot's bindings. The controller layout mirrors the real pad, including the DualSense Edge paddles and FN buttons as chips. The MIDI instrument shows a seven-octave keyboard shaded by velocity, a named dial for every knob, pitch bend and aftertouch meters, a 16-channel activity strip, and a rolling event log.
Click to jump
Click any control in the visualizer and the editor opens at its row. The row numbers in the editor match the numbers shown next to controls in the visualizer, so the two are always the same map.
Edit Layout
Press Edit Layout to drag widgets around, resize them, and save an arrangement per controller model. Zoom and pan with the slider or the trackpad. A layout that puts the stick you use most at the top is a small thing that makes calibration and troubleshooting faster.
Reading it for troubleshooting
- A control that does not light up is not reaching the Mac: check the connection, the mode switch, or the Access Controller's profile.
- A stick that sits off centre at rest is drifting; that is the number to put in its deadzone.
- A trigger that shows a few percent at rest needs a small inner deadzone before it stops firing.
- The tap detector's level for Tap the Mac shows whether a knock registered.
Questions
Does the visualizer cost performance?
It only draws when data changes and it is off while the editor sheet is open. On an idle controller it uses nothing.
Can I see a controller that is connected but not in the preset?
Yes. Every connected device gets a panel whether or not the preset binds it.
