I sold my SD7. Ketron not buy ever again. With this attitude to customers - let thei play on it.
Good wishes for all
Policy with Ketron and many other companies in the music branch is to only communicate trough their dealers.....
(Same goes for Yamaha, tough recently the yamaha synth division appointed a relations manager on the yamaha synth site... Tough Montage/Motif/moxf only, not for arrangers)
Communicate trough your reseller, thats the best way to go... Sadly many internet shops dont give any kind of aftersales support.
