WIDI Master adds wireless Bluetooth MIDI transmission and reception functions to music equipment with MIDI DIN connectors. This product consists of two parts: one is the main adapter, which is used to obtain power from MIDI OUT DIN connector and send or receive MIDI messages wirelessly. The other is a sub adapter, which is used to transmit MIDI messages to the MIDI IN DIN connector of the MIDI device.

WIDI Master can be used with MIDI DIN connectors of MIDI devices that apply to the MIDI standard, such as: synthesizers, MIDI controllers, MIDI interfaces, keytars, electric wind instruments, v-accordions, electronic drums, electric pianos, electronic portable keyboards, audio interfaces, digital mixers, etc. At the same time, WIDI Master can also connect devices and computers with a built-in BLE MIDI feature, such as: Bluetooth MIDI controllers, iPhones, iPads, Mac computers, Android mobile phones, PC computers, etc.

WIDI Master main adapter comes with LED indicators. When power is on, the LED will be lit. When the LED is blue, it means that the device is in normal working condition. When the LED light is green, it means that the device is waiting for a firmware upgrade.

Add WIDI Master Bluetooth MIDI function for standard MIDI devices

1. Plug the 2.5mm mini jack connector of WIDI Master's sub adapter into the mini jack socket of the main adapter.
2. Plug WIDI Master's main adapter into the MIDI OUT DIN connector of the MIDI device, and plug the sub adapter into the MIDI IN DIN connector.

Note: If the MIDI device only has a MIDI OUT DIN connector, there is no need to connect the mini jack connector and sub adapter.

Note: If the MIDI OUT DIN connector of the MIDI device is not able to provide 3.3v~5v power, please visit WIDI website for information about the DIY power supply cable.

Connect two WIDI Masters

1. Turn the power on of both MIDI devices equipped with WIDI Master.
2. The two WIDI Masters units will pair automatically, and the blue LED will change from slow flashing to constant light (when there is MIDI data sending, the LED light will flash dynamically).

Connect WIDI Master with Bluetooth MIDI device

1. Turn on both the MIDI devices plugged with WIDI Master as well as the Bluetooth MIDI devices.
2. WIDI Master will automatically pair with the Bluetooth MIDI device, and the blue LED will change from slow flashing to constant light (when there is MIDI data sending, the LED light will flash dynamically)

Note: If WIDI Master cannot automatically pair with another Bluetooth MIDI device, it may be caused by a compatibility issue. In that case please contact CME for technical support.

Connect WIDI Master with Windows 10
First, the music software must integrate Microsoft's latest UWP API to use the Bluetooth class compliant MIDI driver that comes with Windows 10. Most music software has not yet integrated this API for various reasons. As far as we know, only Cakewalk by Bandlab currently integrates this API, so it can directly connect to WIDI Master or other standard Bluetooth MIDI devices.

Of course, there are some alternative solutions for MIDI transmission between the Windows 10 Bluetooth MIDI driver and music software through virtual MIDI port software applications, such as LoopMIDI and MIDIberry. This approach adds a small amount of latency and some limitations, but it can be used to meet basic connection requirements.

In addition, we have developed WIDI UHOST as a professional hardware solution for Windows users, that meets the requirements of professional users for ultra-low latency and long-distance control to the greatest extent. Please visit WIDI websitefor details.

Connect WIDI Master with Android device
Like the case of Windows, the Android Music App must integrate the universal Bluetooth MIDI driver of Android's OS to communicate with the Bluetooth MIDI device directly. Most music apps haven't integrated this functionality for various reasons. Therefore, you need to use specific apps dedicated to connecting Bluetooth MIDI devices as a bridge.

1. Turn on the power of the MIDI device with the WIDI Master plugged in, and confirm that the blue LED flashes slowly.
2. Turn on the Bluetooth function of the Android device.
3. Go to the PlayStore to search and download the free application [MIDI BLE Connect].
4. Open the MIDI BLE Connect App, click [Bluetooth Scan], find the

WIDI Master that appears in the list, and click [WIDI Master], it will show that the connection is created successfully. At the same time, the Android system will send a Bluetooth pairing request notification. Please click on the notification and accept the pairing request. After this you can press the Home button on the Android device to minimize the MIDI BLE Connect App and keep it running in the background.

5. Open the music app that accepts an external MIDI input, and select WIDI Master as the MIDI input device on the settings page, then you can start using it.

FAQ

The LED of the main adapter of WIDI Master is not lit.

• Is the main adapter connected to the MIDI OUT jack of the MIDI device?
• Has the MIDI device been turned on?
• Does the MIDI OUT DIN connector of MIDI device supply power? You can ask the manufacturer of the MIDI device for relevant information.

Can I connect the sub adapter of WIDI Master to the MIDI IN DIN connector alone when I only use MIDI IN?

• The sub adapter cannot work as standalone and must be connected with the mini jack of the main adapter.

Can WIDI Master connect wirelessly with other BLE MIDI devices?

• If the BLE MIDI device complies with the standard BLE MIDI specification, it can be connected automatically.

The wireless connection distance is very short, or the latency is large, or the signal is intermittent.

• WIDI Master uses the Bluetooth standard for wireless transmission. When the signal is strongly interfered or obstructed, the transmission distance and response time will be affected by objects in the environment, such as trees, reinforced concrete walls, or environments with more electromagnetic waves.
