When it comes to wireless MIDI, the most commonly used is Bluetooth MIDI. Bluetooth MIDI is a MIDI protocol designed by Apple in 2014 and listed as an industry standard by MMA members in June 2015.This allows many musical instruments to be seamlessly connected to mobile phones, tablets, computers and other devices through wireless Bluetooth, eliminating the need for complicated connections, and also convenient for composing and practicing.

At present, most electronic musical instruments only have MIDI interface and USB MIDI interface, but do not have the wireless Bluetooth MIDI function. Therefore, to realize the Bluetooth MIDI connection, a Bluetooth MIDI converter is needed.And the following introduces this product, which is a Bluetooth MIDI adapter for USB MIDI interface conversion-DOREMiDi's USB to Bluetooth adapter "UTB-21".

Product connection

There is a USB printer plug on the UTB-21 (actually called a USB-B plug), which is used to connect to the USB MIDI interface of the musical instrument.At present, most USB interfaces on electronic musical instruments use this printer interface, which has the characteristics of durability and reliable connection.Of course, because of the relatively large volume, some musical instruments pursue small size and use small USB ports, but the functions are the same.

The USB flat plug of UTB-21 (actually called USB-A plug) is used to power the product. DOREMiDi officially provides two power supply methods, one is powered by a 5V adapter (you can use the adapter that comes with our mobile phone)), this kind of need to pull the cord to the socket; one is to supply power through the battery box, as long as 3 ordinary AAA batteries, it can realize true wireless use.

Product use

There are many APPs with Bluetooth MIDI function. Here we mainly use the iPhone’s Garageband as a test. It should be noted that Bluetooth MIDI needs to be connected in the APP, not in the system settings.

First, turn on the Bluetooth function of the iPhone, and then turn on the Garageband software, as shown in the figure:

Find the settings in the upper right corner, click Open→click Bluetooth MIDI device→find DOREMiDi connection→show connected, then the connection is successful, and then use GarageBand's instrument to create!

For those who are learning the piano, I recommend playing piano, bubble piano, and easy-to-play piano, all of which have Bluetooth MIDI function.
