4. Setup Guide
The summina Wireless MIDI Adapter is designed for plug-and-play operation. Follow these steps to set up your device:
- Charge MIDI A Unit: Before first use, ensure the MIDI A unit (the one with the IN/OUT cables) is fully charged using the provided USB charging cable. Connect the micro-USB end to the MIDI A unit and the USB-A end to a power adapter or computer USB port.
- Connect MIDI A: Plug the 5-pin DIN "OUT" connector of the MIDI A unit into the MIDI OUT port of your MIDI device (e.g., keyboard, controller). Plug the 5-pin DIN "IN" connector of the MIDI A unit into the MIDI IN port of your MIDI device.
- Connect MIDI B: Plug the MIDI B unit (USB dongle) into a USB port on your computer, tablet, or smartphone. This unit acts as the receiver and typically draws power directly from the USB port.
- Power On: Turn on your MIDI devices and ensure the MIDI A unit is switched on (if it has a power switch).
- Automatic Connection: The MIDI A and MIDI B units will automatically establish a wireless connection. No manual pairing is typically required for point-to-point operation.
- Software Recognition: Your computer or mobile device should recognize the MIDI B unit as a standard MIDI input/output device. You can then select it within your Digital Audio Workstation (DAW) or MIDI software.

5. Operating Instructions
Once set up, the summina Wireless MIDI Adapter functions as a transparent MIDI cable, transmitting MIDI data wirelessly between your devices.
- MIDI Data Transmission: Any MIDI messages (note on/off, control changes, program changes, etc.) sent from the MIDI OUT of your instrument will be wirelessly transmitted to the MIDI B unit and then to your connected computer/device. Similarly, MIDI messages from your computer/device will be sent to the MIDI B unit and then wirelessly to the MIDI IN of your instrument.
- Latency: The system is designed for ultra-low latency (as low as 3ms), ensuring a responsive playing experience.
- Battery Life (MIDI A): The MIDI A unit's built-in rechargeable battery provides extended usage. Monitor the indicator light (if present) for battery status. Recharge as needed.
- Power (MIDI B): The MIDI B (USB dongle) unit is powered directly by the USB port it's connected to.
