The Roland AE20 thumb cross wheel has been changed to an up and down lever, and two optional thumb sleeves have been added. Bluetooth can be used for reception, but not transmission. There is no midi port like the AE30, and the workmanship looks much better than the AE10, similar to the AE30. The settings screen has Chinese characters and a volume adjustment knob. The sounds (now called ‘Scenes’) include Roland’s ‘Supernatural Sounds’, as well as synthesizer sounds (ZEN Core). You can download scenes from the ‘Roland Cloud’ and adjust the scenes using a Bluetooth-connected app.

The Roland AE-20 offers all the playability and expressiveness of Roland’s top-of-the-line Aerophone Pro in a more compact, streamlined design. Rich in musical experience, premium detail and Roland's state-of-the-art sound engine, this inspiring modern wind instrument brings a new level of energy and versatility to all creative journeys.
