Hi Lee S
The OAS engineers work for Music Store.

You can try Ralph Conti, http://www.wersimusic.com/contact.html but I do not know whether he currently has any connections with Music Store.

Another way is to contact Wersi Direct GB http://www.wersidirect.com/www.wersidirect.com/Contact_US.html who will have more details.

Alternatively contact Music Store Direct http://www.musicstore.de/is-bin/INTERSHO...iewEmailer-View

Hope this helps

Bill
