In this thread i followed the discussion.
My KPA has showed some erratic behaviour recently. it took 5 minutes and three tries to upload ten profiles.
After bootup there was only one rig on the KPA. rebooting solved this.
Somehow the loudness of the S/PDIF output has changed.
I format my PC on a regular basis, so why not give my KPA a fresh OS after 20 months?
Or do you say: dont fix it, if it ain't broke?
Anyway: see above< what is the best and safest method to reset my baby?
