I am glad we don't have the same issues in the UK. The only problem from my point of view is that we have lost a couple of sales because of Synthzone.
I stand by what I have said though. Ketron Italy have worked closely with us. Sometimes they do not understand due to language difficulties so we have to persevere. However much of the problems experienced by owners here could be avoided by the distributor stocking parts (as ketron UK do).
One thing I have learned is not to rely on emails completely as its not unusual for them to get lost in the system (I have about 6000 emails per week go into my junk box - I still have to scan through them as customers messages sometimes end up in there). Often its simpler just telephone the factory directly.
