Problem with casio Privia PX-870

[MusicMerci]

Hello
I use the app with Casio Privia PX-870.
The setting is done, the indicator is lighting up when I press keys but the zone of master 1 is not yet set to ON.
Then I set to ON the zone of master 1, but the time I press any keys on the keyboard, the app crashes.
I tried the app with my Roland BK5 and there is no problem, no crashes. The extern 1 app is BASSalicious 2 and it works fine.
It seems the crashes is only with the Casio.

Refer to the midi data received from the Roland and the Casio in the attachment.


Please need help. Thank You.

Best regards.
