I have to reply to these posts. First I do not own a SD9 Pro and have not had a chance to play one in person. I do however own 2 Ketron SD7s and have had them for about 3 years. So far I have not had a single problem with either of the two SD7s. I have converted thousands of legacy Ketron styles on the SD7 with no problems at all. That said, NONE of the Audya styles would convert. I play midi files, MP3 files, WAV files and all play without a single issue. I have played live gigs with the SD7s for three years - never once have I had a problem.

Maybe I am missing something here in Henni's post but as far as the SD7 is concerned I can highly recommend it to anyone.
