Sorry for the double post, but the first try is barely readly because of html tags... :( Thank you Clemens for your fast reply. Sorry for the weird remark regarding /var/log/messages. To clarify: I was *not* able to find related errors. One thing I have seen while watching the data received by amidi with the -d option as well as with the other tools was, that the "data stream" sometimes seems to stop while the Axe-Fx II is still sending data. Sometimes the stream continues after or short break, sometimes it does not. Don't know if this could be a timing issue? Regards, Joachim > Gesendet: Donnerstag, 11.
