【DOREMiDi】New Bluetooth 5.0 MIDI Adapter Pro——MTB-22 Pro&UTB-21 Pro

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 two products are introduced,-DOREMiDi's USB to Bluetooth MIDI adapter "UTB-21 Pro" and MIDI to Bluetooth MIDI adapter "MTB-22 Pro".

Product use

There is a USB square plug (also called USB-B plug/printer interface) on the UTB-21 Pro, which is used to connect 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 efficient transmission of Bluetooth 5.0 can also bring the speed of MIDI signal processing as low as milliseconds., In order to ensure that everyone can stay on the chain while playing, and be more calm.

Note for MIDI connection, the IN of the MIDI cable is connected to the OUT port of the instrument, and the OUT of the MIDI cable is connected to the IN port of the instrument.

It adopts the design of MIDI port to take power. If the MIDI output port of your instrument has a 5V power supply function, then the MTB-22 Pro can be directly powered through the MIDI port of the instrument to achieve true MIDI wireless transmission.

If the power supply on the MIDI interface of the MIDI device is insufficient or does not have any power supply function, the product can be powered through the Micro USB interface. (You can use the built-in Micro USB power supply port).
