V. Setting up a MIDI Controller
Preparation
- Use the device’s included USB cable.
- If your device uses a 5-pin DIN cable, you may need to use a DIN-to-USB converter or interface. (fig.1)

- If your device needs a driver, install it first; many USB-MIDI devices are class-compliant and need no driver. For more information check the user manual of your device.
2. Plug in
- USB: Connect the device to the computer (directly or via a powered hub).
- 5-pin DIN: MIDI OUT of the device → MIDI IN of your audio/MIDI interface; connect the interface to the computer via USB (see fig.1).
- Bluetooth MIDI: Put the device in pairing mode and...
macOS: Open Audio MIDI Setup → Window › Show MIDI Studio → Bluetooth and connect.
Windows: Settings → Bluetooth & devices → Add device to pair. For BLE-MIDI routing, you can use Microsoft’s BLE-MIDI Connect app.
Linux: BLE setups vary; if you’re new to Linux MIDI, prefer USB for reliability (then proceed to step
3. Confirm connection
macOS: Open Audio MIDI Setup → Show MIDI Studio; your device should appear. (You can also create/edit configurations there.)
Windows: After pairing/plugging in, the device will show in your DAW’s MIDI preferences.
Linux (ALSA): List ports: aconnect -l. Inspect incoming data with aseqdump -p <client:port>. Tell your DAW to use it.
4. To use on your DAW
- Open your DAW’s Preferences/Settings → MIDI.
- Enable the device as an input (“Track” or “Input From”). Some DAWs (such as Ableton Live), require that you add a virtual instrument to enable gain, send and receive options (fig.2-3).
Fig. 2 In Ableton, MIDI tracks without a softsynth will show a disabled gain, output, and sends.
Fig. 3 Adding a softsynth or virtual instrument will automatically enable gain, output and sends on the MIDI track.
- If you want to map knobs/faders, also enable control/Remote on that input; enable output/feedback only if the controller supports it.
- Make a quick test trackCreate a MIDI/Instrument track and load a built-in synth
- Set input to All Channels (or the device’s channel), arm the track, enable monitoring, and play—your MIDI meter should move. If nothing happens, go back to "confirm connection" and check that any required drivers are installed.
5. Custom-map knobs & pads.
- Enter your DAW’s MIDI Learn/Map mode and twist or push a control to bind it.
6. Syncing multiple MIDI devices
- Clock/transport sync (optional)If you need external devices tempo-locked, enable Sync on the correct port in your DAW:Ableton Live: Preferences → Link/Tempo/MIDI → Sync (In/Out) as needed.
- To route MIDI between apps, enable the IAC Driver in Audio MIDI Setup → MIDI Studio → IAC Driver → “Device is online.”
