Dirk,
thank you for your information; I really appreciate your honesty and hope that Ketron can fix the noise problem.
JCKeeys, I used headphones in my audio test of the SD1, so I guess that we can rule out the speakers/amplifier factor.
I am curious to hear your impressions too about this keyboard.
Regards
Andrea
