Hello Bug ?
Windows 10 64 bits,
C3 performer 3640,
Keyboard Roland FA08 usb plug with th PC.
My piano FA08 send program change to change the songs.
When i send quikly a lot of program change, the communication usb with my keyboard stop. I can’t close C3, i have to kill it with Ctrl-Alt-Del.
I must unplug the USB cable et again plug it et open C3.
The solution is to send one program change and wait 1 second and send another and wait 1 seconde…
