Where can I get the app of Roland electric blowtorch AE20?

I downloaded it from Roland official website and found many improvements. The thumb cross wheel is changed into an up-and-down pull rod, and two optional thumb covers are added. Bluetooth can be used to receive, but not to transmit.

There is Chinese on the setting screen of the volume adjustment knob. Timbre includes Roland's supernatural timbre and synthesizer timbre. You can download the scene from Roland and adjust the scene with Bluetooth connection.
