Hi,
Apparently it is not a general issue because many people do not experience this problem. Till now we do not have a clear cut repro to reproduce. We have idications that the problem is related to MIDI over Lan, IAC Bus/MID Over LAN, Lemur or TouchOSC drivers. Is any of you using MIDI over Lan, or TouchOSC or Lemur?
Greetings,
JHP
