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

When it comes to wireless MIDI, the most commonly used one 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, which saves complicated connections and facilitates composition and practice.

At present, most electronic musical instruments only have MIDI interface and USB MIDI interface, but no wireless Bluetooth MIDI function, so to realize the connection of Bluetooth MIDI, a Bluetooth MIDI converter is required. 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

At present, most of the USB interfaces on electronic musical instruments use this type of printer interface, which has the characteristics of durability and reliable connection. Of course, because of the relatively large size, some musical instruments pursue small size and also use small USB ports, but the functions are the same.
