Oh man! After look and try many usr relevant settings I found the malfactor: 
tlp usb autosuspend settings.

I use tlp (energy-saving tools for thinkpad laptops) and they autosuspend usb 
devices by default. Now I have blacklisted my midi keyboard an all is good. I 
can reproduce the problem this way. Seems so that the midi keyboard doesn't 
wake up if it once sleeping.

For all with similar problems: 
edit /etc/default/tlp and set USB_BLACKLIST="<device id from usbls>" or 
disable usb autosuspend entirely with USB_AUTOSUSPEND=0

thanks and sorry for the bother.
