Hi,
Thank you for the comments!

1-A small parenthesis:
do you have an idea of the next update?Other,
Yesterday I used the PRO3 connected via USB as a midi keyboard to drive a virtual synthesizer...
2-The problem encountered: when playing on the keyboard, after a certain time (a few minutes), when I press one of the keys on the keyboard the sound cuts out and when I release the note, the sound is triggered and the time that I do not recover the sound remains active. The solution is to turn the device off and on again.

Musically
