ℹ

Any MIDI Controller

Even if your controller isn't listed, you can use MIDI Learn to create a custom mapping. Any class-compliant MIDI device will work.

Connecting Your Controller

USB Connection

Connect your controller to your device via USB (use a USB-C adapter if needed)
Power on the controller
Tremor auto-detects the controller and loads the mapping
You'll see a notification: "Controller Connected"

Bluetooth Connection

Put your controller in Bluetooth pairing mode
Open iOS Settings → Bluetooth
Tap your controller when it appears
Once paired, Tremor detects it automatically

💡

USB is Better

Bluetooth adds ~20ms latency. For professional performance, always use USB. Bluetooth is fine for practice and casual mixing.

MIDI Learn

Create custom mappings for any control in Tremor:

Go to Settings → MIDI → MIDI Learn
Enable Learn Mode
Tap an on-screen control (e.g., the EQ Low knob)
Move the physical control on your controller
They're now linked! The mapping saves automatically.

You can export your custom mapping to share with others, or import mappings created by the community.

4-Channel Controllers

Controllers like the DDJ-FLX10 and DDJ-GRV6 have 4 channels. In Tremor:

Use 4-Deck mode on iPad to see all 4 decks with the Orbital Fader
On iPhone, use the DECK SELECT buttons to switch which deck pair is visible
All 4 decks are always active — DECK SELECT just changes what you see
