2. Product Overview
Familiarize yourself with the various components and controls of your SMK-37 Elite MIDI keyboard.

2.1 Back of Device
- Audio Output: 3.5mm audio output jack for connecting headphones or external speakers.
- MIDI Output: 3.5mm standard MIDI adapter port for connecting to external MIDI devices.
- Power: Switch to turn the MIDI keyboard on or off.
- USB: USB-C connection port for power and MIDI data transfer.
- Sustain: 1/4 inch jack for connecting a sustain pedal.
2.2 Front Panel Controls
- Pitch Wheel and Modulation Wheel:
- Pitch Wheel: Scroll the pitch stripe up and down to control pitch bend. The center position represents the original pitch. Releasing the stripe returns the sound to its original pitch.
- Modulation Wheel: Scroll the modulation wheel to send continuous MIDI CC messages. This can often be assigned to various parameters in your Digital Audio Workstation (DAW) using MIDI Learn.
- Display Area: A 1.54-inch color display provides visual feedback for various device settings and modes.
- Button Area:
- Knob Bank: Press to switch control to knobs 9-16.
- Fader Bank: Press to switch control to faders 5-8.
- Pad Bank: Press both Knob Bank and Fader Bank buttons simultaneously to switch control to pads 9-16.
- Left Button: Sends custom MIDI messages or accesses specific functions.
- Right Button: Sends custom MIDI messages or accesses specific functions.
- Knobs: Eight assignable 360-degree rotary encoders. These can send Aftertouch, MIDI CC, or pitch information, configurable via the MIDI SUITE software.
- Pads: Sixteen RGB backlit pads with velocity-sensitive and aftertouch capabilities.
- Faders: Four assignable faders for controlling parameters like volume, pan, or MIDI CC values in your DAW or device software.
- Button Area 2 (Arp): Press the ARP button to enable the Arpeggiator. To adjust Arpeggiator parameters, press and hold the ARP button while rotating a knob or pressing specific keys.
3. Initial Setup
3.1 Unpacking and Powering On
- Carefully remove the SMK-37 Elite from its packaging.
- Locate the Power switch on the back of the device (refer to Figure 2.1, item 3).
- Switch the power to the 'ON' position. The device can be powered by its internal battery or via the USB-C port.
3.2 Connections

- USB Connection: Connect the supplied USB-C cable from the SMK-37 Elite's USB port (Figure 2.1, item 4) to your computer or a USB power adapter. This provides power and enables MIDI communication with your computer.
- MIDI Output: Use a 3.5mm standard MIDI adapter cable to connect the MIDI Output port (Figure 2.1, item 2) to the MIDI In port of an external MIDI device.
- Audio Output: Connect headphones or speakers to the 3.5mm Audio Output jack (Figure 2.1, item 1) to monitor the built-in synthesizer sound.
- Sustain Pedal: Connect a 1/4-inch sustain pedal to the Sustain port (Figure 2.1, item 5) for expressive control.
3.3 Wireless Bluetooth MIDI Connection

The SMK-37 Elite supports wireless Bluetooth MIDI connectivity with Windows, Mac, iOS, and Android devices.
- Ensure Bluetooth is enabled on your host device (computer, tablet, or smartphone).
- On your host device, search for available Bluetooth MIDI devices.
- Select 'SMK-37 Elite' from the list to pair.
- For Windows users, Bluetooth 5.0 is recommended, and an additional BLE MIDI Driver may be required.
4. Operation
4.1 Playing the Keys and Pads

- Keys: The 37 velocity-sensitive keys respond to how hard you press them, allowing for dynamic musical expression.
- Pads: The 16 RGB backlit pads are velocity-sensitive and support aftertouch. Use them for drumming, triggering samples, or playing chords.
- Pad Bank: To access pads 9-16, press both the Knob Bank and Fader Bank buttons simultaneously.
4.2 Using Encoders and Faders


- Rotary Encoders: The 8 endless rotary encoders can be assigned to control various parameters in your DAW or internal synthesizer. Use the Knob Bank button to switch between different sets of parameters (e.g., knobs 1-8 and 9-16).
- Faders: The 4 assignable faders provide tactile control over parameters like volume, pan, or filter cutoff. Use the Fader Bank button to expand control to 8 faders.
4.3 Arpeggiator and Note Repeat

- Arpeggiator: Press the ARP button to activate the arpeggiator. It will automatically play a sequence of notes based on the chord you hold. Adjust arpeggiator parameters by holding the ARP button and rotating an encoder or pressing specific keys.
- Note Repeat: The Note Repeat function allows for rhythmic repetition of notes.
4.4 Built-in Sequencer

The SMK-37 Elite includes a built-in sequencer that supports saving up to 8 patterns. This allows you to create and play back note patterns step-by-step or in real-time. Note: When Arpeggiator and Note Repeat are enabled, the sequencer cannot be activated.
4.5 Internal Sound Source (FM Synthesizer)

The SMK-37 Elite features a built-in FM synthesizer. Connect headphones or speakers to the Audio Output jack to hear the internal sounds without needing an external computer or DAW.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the surface of the keyboard. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. If storing for an extended period, charge the battery to approximately 50% and recharge every few months.
- Avoid Liquids: Keep the keyboard away from liquids to prevent damage to internal components.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power switch off, low battery, or USB cable not connected/faulty. | Ensure power switch is ON. Charge the battery via USB-C. Check USB cable connection. |
| No sound from internal synth | Headphones/speakers not connected, volume too low, or incorrect audio output selected. | Connect headphones/speakers to the 3.5mm Audio Output. Increase volume. |
| MIDI not recognized by computer/DAW | USB cable issue, incorrect DAW settings, or Bluetooth not paired. | Check USB cable. Ensure MIDI input is enabled in your DAW. Re-pair Bluetooth connection. Install necessary drivers for Windows. |
| Keys/pads not responding | Device frozen, incorrect mode selected. | Try turning the device off and on again. Ensure you are in a playable mode. |
| Arpeggiator/Sequencer not working | Conflicting functions enabled. | Ensure Arpeggiator and Note Repeat are not simultaneously active when trying to use the sequencer. |
