Turn a second device into a physical control surface. One Sonyk hosts, another connects over the local network, and the controller's keys, pads, chord strips and XY pad play the host's engine — notes take a direct, low-latency path so it feels like an instrument rather than a remote.

• Host advertises on your network; the controller lists it by device name.
• A round-trip latency badge on the controller tells you the truth about your link.
• On Vision Pro the headset is the host — switch it on in Settings, then open Sonyk on the iPad and pick it.
