CONNECTION

Please note: The first batch of WIDI Master shipped with firmware version 0.0.4.4. If you unconsciously pressed the button during normal use, it will switch the unit to the test mode (deactivated) and as a result unable to be used normally. In this case, please go to BluetoothMIDI.com to install WIDI App on your iOS or Android device to activate it. WIDI Master is a wireless Bluetooth virtual MIDI cable. It adds Bluetooth MIDI (transmitting and receiving) to music equipment with MIDI DIN connectors, 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. The WIDI Master 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.

There is a push switch on the main adapter of WIDI Master, it is used for the following quick operations (please confirm that the product firmware has been upgraded to the latest version). The following operations are based on firmware v0100 or higher:

•  When the WIDI Master is NOT powered on, press and hold the button. Power on the WIDI Master until the green LED light flashes slowly for 3 times. Then release the button. The device will manually reset to the factory default.
•  When the WIDI Master is powered on, press and hold the button for 3 seconds and then release it. The device will be manually set to “force peripheral” mode. If the WIDI Master was connected to other BLE MIDI devices, this connection will be terminated by following this procedure.

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 driver, such as Korg BLE MIDI driver. Starting from the firmware version v0.1.3.7, WIDI is fully compatible with the Korg BLE MIDI Windows 10 driver. It can support multiple WIDIs connected to Windows 10 computers at the same time with two-way MIDI data transmission. The operations are as follows:

Video instruction: https://youtu.be/JyJTulS-g4o

1. Please visit Korg’s official website to download the BLE MIDI Windows driver. https://www.korg.com/us/support/download/driver/0/530/2886/
2. After decompressing the driver files with the decompression software, click the exe file to install the driver (you can check whether the installation is successful in the sound, video, and game controller list of the device manager).
3. Please use the WIDI App to upgrade the firmware of the WIDI device to v0.1.3.7 or later (for upgrade steps, please refer to the relevant instructions and videos on BluetoothMIDI.com). At the same time, please set the upgraded WIDI BLE role to “Forced Peripheral” to avoid automatic connection when multiple WIDIs are used at the same time. If necessary, you can rename each WIDI after the upgrade, so that you can distinguish between different WIDI devices when you use them at the same time.
4. Please make sure that the Windows 10 and the Bluetooth driver of your computer has been upgraded to the latest version (the computer needs to be equipped with Bluetooth 4.0/5.0 capability).
5. Plug a WIDI into the MIDI device, turn on the power to start the WIDI. Click “Start” – “Settings” – “Devices”, open the “Bluetooth and other devices” window, turn on the Bluetooth switch, and click “Add Bluetooth or other devices”.
6. After entering the Add Device window, click “Bluetooth”, click the WIDI device name listed in the device list, and then click “Connect”.
7. If you see “Your device is ready to go”, please click “Done” to close the window (after connecting, you can see WIDI in the Bluetooth list of the device manager).
8. Please follow steps 5 to 7 to connect other WIDI devices to Windows 10.
9. Open the music software, in the MIDI settings window, you should be able to see the WIDI device name appearing in the list (Korg BLE MIDI driver will automatically detect the WIDI Bluetooth connection and associate it with the music software). Just select the desired WIDI as the MIDI input and output device.

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 www.cme-pro.com/widi-uhost for 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.

Group connection with multiple WIDI devices

WIDI Master supports group connection from firmware version v0100 and higher. Group connections will allow two-way data transmission of 1-to-4 MIDI  Thru and 4-to-1 MIDI merge. And it supports simultaneous use of multiple groups.

Video instruction: https://youtu.be/ButmNRj8Xls

1. Go to the iOS Appstore to search for and download the free application WIDI App.
   （Version 1.2.19 or higher）

2.  Upgrade WIDI Master to the latest firmware. Then keep only one WIDI Master powered on.
   Note: Please remember to avoid having multiple WIDI Masters powered on at the same time. Otherwise, they will be automatically paired one to one. This will cause the WIDI App to fail in finding the WIDI Master you want to connect to as they are already occupied.

3. Set your WIDI Master as “force peripheral” role and rename it.
   Note 1: After the BLE role is set as “force peripheral”, the setting will be automatically saved in the WIDI Master.
   Note 2: Click the WIDI Master device name to be renamed. The new name will be effective once restarted.

4. Repeat the above steps to set all WIDI Masters to be added to the group.

5. After all WIDI Masters are set to the “force peripheral” role, they can be powered on at the same time.

6. Click the “Group” menu, and then click “Create New Group”.

7. Enter the name of the group.

8. Drag and drop the WIDI Master to the central and peripheral positions.

9. Click “Download Group”. The setting will be saved in all WIDI Masters. From here on, these WIDI Masters will be restarted and automatically connect as the same group by default.

Note 1 : Even if you power off the WIDI Master, all the group setting status will still be remembered. When you power them on again, they will be automatically connected in the same group.
Note 2: If you want to forget the group connection settings, please use the WIDI App to connect to the WIDI Master with “Central” role and click “Reset Default Connections”. Again, only power on this central device to allow the pairing with WIDI App. If you power on multiple group devices they will automatically connect as a group. This will make it impossible for the WIDI App to make to connection as they will already be occupied.
